For further information or clarification regarding the appropriate use of our products, please contact NUPEX customer support directly.
How do I calculate the correct dosage for a specific peptide?
All peptides supplied by NUPEX are strictly intended for laboratory and research use only. As such, dosage calculation refers exclusively to determining precise concentrations required for controlled experimental conditions.
To accurately calculate peptide concentration for your research:
Identify the peptide quantity:
Refer to the product label provided by NUPEX, which clearly indicates the amount of peptide present in milligrams (mg).
Reconstitution of the peptide:
Typically, peptides are supplied in a lyophilised (freeze-dried) powder form and
must be reconstituted with an appropriate sterile solvent, commonly
bacteriostatic water or sterile distilled water.
(Note: Always confirm the optimal solvent based on peptide properties and
research guidelines.)
Calculate peptide concentration:
Peptide concentration can be calculated using the following formula:
Peptide Concentration (mg/ml)=Total peptide weight (mg)Volume of solvent added (ml)\text{Peptide Concentration (mg/ml)} = \frac{\text{Total peptide weight
(mg)}}{\text{Volume of solvent added
(ml)}}Peptide Concentration (mg/ml)=Volume of solvent added (ml)Total peptide
weight (mg)
For example, if your vial contains 5 mg of peptide and you add 2 ml of solvent,the peptide concentration would be:
5 mg2 ml=2.5 mg/ml\frac{5\,\text{mg}}{2\,\text{ml}} = 2.5\,\text{mg/ml}2ml5mg=2.5mg/ml
Conversion to micrograms (μg):
If your research protocol requires peptide concentrations in micrograms (μg),
remember:
1 mg=1000 μg1\,\text{mg} = 1000\,\text{μg}1mg=1000μg
Therefore, 2.5 mg/ml would equal 2500 μg/ml.
Important Note:NUPEX peptides are provided exclusively for research and laboratory purposes. We are
unable to provide guidance or advice regarding the administration, injection, or human
usage of peptides. It is the researcher's responsibility to adhere to all local regulations,
safety protocols, and ethical guidelines when conducting research involving peptides.
For further technical or product-related enquiries, please contact NUPEX customersupport.
Why does my peptide vial appear nearly empty upon arrival?
Peptides supplied by NUPEX are provided in lyophilised (freeze-dried) powder form, significantly reducing their volume while enhancing stability during storage and shipping. Lyophilisation removes all moisture, resulting in a highly concentrated, very fine powder. Consequently, the amount of powder in the vial might seem minimal, often not fully covering the base of a standard laboratory vial.
We can confirm the peptide quantity stated on your vial is accurate. For example, if your order specifies precisely 5 mg of peptide, this amount is exact. To maintain stability and protect the delicate amino acid structure of peptides such as, we combine 5 mg of the peptide with 45 mg of mannitol as a stabilising agent, resulting in a total of 50 mg of powder. To illustrate this further, consider that a teaspoon of sugar weighs approximately 4,000 to 5,000 mg; thus, the total 50 mg content in your vial represents only a tiny fraction of this, explaining why it may visually appear minimal.
Your previous experiences may have involved peptides purchased online that were incorrectly labelled or counterfeit. Such products are commonly machine- filled with significantly larger quantities—often over 800 mg—of wet or damp powder that settle densely at the bottom of the vial. These products are invariably compromised and non-viable, as genuine peptides lose integrity when packaged under moist conditions.
Please rest assured that NUPEX peptides are meticulously measured with laboratory balances calibrated multiple times daily, maintaining an accuracy tolerance of ±0.0001 mg. Each vial is manually filled by trained laboratory technicians at the time your order is prepared, ensuring precise and accurate measurements.
If you require further clarification or support, please contact NUPEX customer support directly.
Important Note: All peptides from NUPEX are strictly intended for research and laboratory use only and should always be handled in accordance with laboratory safety guidelines and applicable regulations.
What should I do if the peptide powder is stuck to the sides of the vial?
It is common and completely normal for lyophilised (freeze-dried) peptide powder to adhere to the sides or neck of the vial, due to static electricity or the manufacturing and shipping processes. This does not affect the peptide's integrity, quantity, or quality.
To ensure you fully recover all the peptide powder for your research, follow these recommendations:
Gentle tapping:
Before opening the vial, gently tap it several times against a stable surface or lightly flick the vial with your finger. This will help dislodge powder adhering to the glass surfaces and collect it at the bottom of the vial.
Centrifugation (optional but effective):
If gentle tapping does not fully collect the powder, briefly centrifuge the vial at low speed. Centrifugation efficiently consolidates powder particles at the base of the vial without compromising peptide stability.
Reconstitution procedure:
When reconstituting your peptide with an appropriate solvent, ensure the solution washes down any residual peptide adhering to the sides of the vial. Allow sufficient time for complete dissolution, as certain peptides may take longer to fully dissolve.
NUPEX peptides are meticulously measured and quality-controlled to ensure accurate amounts and exceptional purity. Adherence to vial surfaces is purely a physical phenomenon and does not indicate compromised quality or incorrect measurement.
Should you require additional assistance, please contact NUPEX customer support directly.
Important Note: All peptides supplied by NUPEX are strictly intended for research and laboratory use only and must always be handled in compliance with appropriate safety guidelines and regulations.
Why is the peptide supplied in such a large vial?
Peptides supplied by NUPEX are provided in lyophilised (freeze dried) powder form to ensure optimal stability, purity, and longevity during storage and transportation. During the lyophilisation process, moisture is removed, leaving behind a small amount of fine, highly concentrated powder. Although this powder often occupies minimal volume, larger vials are deliberately chosen for several important practical reasons:
Sterilisation and Safety:
Our 20 ml vials undergo a rigorous sterilisation process prior to being manually filled by trained laboratory technicians. Smaller chromatography vials typically cannot withstand the same stringent sterilisation methods, and thus pose potential contamination risks for peptide samples.
Durability and Storage Requirements:
Larger vials are specifically designed to withstand prolonged storage at very low temperatures (such as -20°C or -80°C). In contrast, smaller chromatography vials are not suitable for such freezing conditions and may crack or split open, compromising the peptide's quality and integrity.
Ease of Handling and Reconstitution:
The larger vial size provides researchers sufficient space to safely add solvents or buffers without spillage or contamination, enabling accurate and efficient peptide reconstitution.
Effective Lyophilisation Process:
The freeze-drying procedure involves creating a vacuum inside the vial. Larger vials help optimise moisture removal and ensure complete drying of the peptide powder, preserving peptide integrity and stability.
Reducing Static and Product Loss:
Larger vials help minimise static charge buildup, reducing the amount of powder adhering to the vial walls and thereby ensuring maximum peptide recovery. Please rest assured that the quantity stated on your NUPEX peptide vial is precisely measured, with our balances calibrated multiple times daily to maintain exceptional accuracy.
Should you require further assistance or additional information, please contact
NUPEX customer support directly. Important Note: All peptides supplied by NUPEX are strictly for laboratory research purposes only and must always be handled in accordance with appropriate safety standards and regulatory guidelines.
What is the correct way to store peptides to ensure optimal stability?
Proper storage is essential to maintain the stability, purity, and integrity of peptides. NUPEX peptides are supplied in lyophilised (freeze-dried) powder form specifically designed for extended shelf life. To achieve optimal peptide stability, please follow the recommended guidelines below:
Storage of Lyophilised (Freeze-Dried) Peptides:
Temperature:
Store lyophilised peptides at -20°C for short- to medium-term storage (up to several months). For long term storage exceeding six months, storage at -80°C is strongly advised.
Protection from Moisture and Light:
Always store peptides in sealed, airtight vials away from moisture, sunlight, or strong artificial light to preserve their integrity and prevent degradation.
Storage of Reconstituted (Mixed) Peptides:
Do Not Refreeze After Reconstitution:
Once peptides have been reconstituted (mixed) with water or an appropriate solvent, they must not be refrozen. Refreezing can cause the vial to crack or split due to expansion pressure from freezing liquids, compromising the peptide and posing a safety risk.
Refrigeration after Reconstitution:
Reconstituted peptides should be stored at +2°C to +4°C (standard refrigeration temperatures). Under these conditions, peptides typically remain stable and suitable for laboratory use for approximately 20 to 30 days.
Labelling for Reference:
Clearly label reconstituted vials with peptide name, concentration, date of reconstitution, and storage conditions to ensure accurate tracking and consistent research results.
General Recommendations:
Ensure all peptide vials remain securely sealed when not in use to prevent contamination or moisture ingress.
Handle peptides using sterile laboratory techniques and protective gloves to maintain product purity.
Always adhere to any additional storage instructions provided with your specific NUPEX peptide product.
By carefully following these storage guidelines, you will preserve peptide stability and integrity, ensuring reliable and consistent results in your research activities. Should you require further information or assistance, please contact NUPEX customer support directly.
Important Note:
All peptides supplied by NUPEX are strictly intended for laboratory research purposes only. Always handle peptides according to applicable safety guidelines, laboratory standards, and regulatory requirements.
Why is the GHK-Cu peptide powder white instead of blue or green?
GHK-Cu peptides supplied by NUPEX are provided in pure, lyophilised (freeze-dried) powder form. Although the peptide contains copper (Cu), the powder itself typically appears white or off-white, rather than the blue or green colour some customers might anticipate.
The blue or green colours commonly associated with copper containing products usually occur in solutions or complexes where copper ions are unbound or loosely bound, allowing the copper to visibly display its characteristic colour. However, in highly pure, lyophilised GHK-Cu peptides, copper ions are strongly and correctly bound within the peptide's molecular structure, resulting in a colourless or white appearance.
Furthermore, it is important to note that some peptide vendors selling cosmetic-grade copper peptides intentionally add food-grade dyes or artificial colouring agents to their products, creating a vivid blue or green appearance. This practice does not reflect the purity or research-grade quality typically required in laboratory settings and is strictly cosmetic in nature.
When correctly reconstituted with sterile water or an appropriate buffer, authentic GHK-Cu peptides may exhibit a subtle, natural pale blue or blue-green tint, indicating the presence of hydrated copper ions.
At NUPEX, we follow rigorous analytical testing and quality control procedures to ensure our peptides' authenticity, purity, and chemical integrity. We do not add artificial colours, dyes, or additives of any kind.
If you have further queries or require assistance, please contact NUPEX customer support directly.
Important Note:
All peptides supplied by NUPEX are strictly intended for laboratory research purposes only and must always be handled in accordance with applicable laboratory safety standards and regulatory guidelines.
What does it mean when a peptide is described as 'tagged'?
When a peptide is described as "tagged," it means that the peptide sequence has an additional short sequence of amino acids, known as a "tag," chemically linked or attached to it. This tag serves a specific practical function in laboratory research and analytical applications, such as improving solubility, facilitating identification, or simplifying the purification process.
Common types of peptide tags include:
Affinity Tags:
These tags (e.g., His tag, FLAG-tag) help in the purification and isolation of peptides or proteins by binding specifically to particular molecules or affinity resins.Fluorescent or Reporter Tags:
Tags such as FITC (fluorescein isothiocyanate) or biotin enable visualisation, tracking, or detection of peptides during laboratory analysis using techniques like microscopy or fluorescence spectroscopy.
Solubility Tags:
Certain tags (e.g., GST tag) can improve peptide solubility or stability, which can enhance experimental performance.
The addition of these tags typically does not significantly alter the core biological or biochemical properties of the peptide itself, but instead makes laboratory handling and research processes more efficient and reliable.
NUPEX supplies a wide range of high-quality, tagged peptides to meet specific research requirements. Each product is clearly labelled and subjected to rigorous quality assurance procedures to ensure reliability and accuracy.Should you require additional information or technical guidance, please contact NUPEX customer support directly.
Important Note:
All peptides supplied by NUPEX are strictly intended for laboratory research purposes only and must always be handled according to appropriate safety protocols and regulatory guidelines.
