• Product Distinction: This CJC-1295 listing contains the C-terminal maleimidopropionyl-lysine modification. The separate product listed as CJC-1295 Without DAC does not contain this modification and has a different molecular formula and molecular weight.
• Counter-Ion or Salt Form: Refer to the applicable Certificate of Analysis, as acetate, trifluoroacetate or another counter-ion may affect net peptide content and the measured mass of the supplied material
• Analytical Interpretation: Chromatographic purity, net peptide content, molecular identity, water content, residual solvent content and counter-ion content are separate analytical measurements and should be interpreted together

✓ Batch documentation – Certificate of Analysis documentation is provided where supplied for review.
✓ Certificate of Analysis – Accessible through the product QR code where provided for the applicable batch.
✓ Safety Data Sheet – Supplied to support appropriate laboratory handling, storage and regulatory compliance.
✓ Sequence documentation – Peptide sequence, residue substitutions and the C-terminal modification should be confirmed using the applicable batch records.
✓ Mass-spectrometry documentation – Molecular identity should be supported by analytical mass data consistent with the specified CJC-1295 construct.
✓ Purity documentation – The reported chromatographic purity applies only to the analytical method and batch stated in the Certificate of Analysis.
✓ Peptide-content documentation – Net peptide content should be distinguished from chromatographic purity and interpreted alongside water and counter-ion results.
✓ Counter-ion documentation – Acetate, trifluoroacetate or another counter-ion should be identified and quantified where applicable.
✓ Supplier documentation – Reviewed where supporting synthesis, purification and analytical records are supplied.
✓ Fast, reliable and trackable delivery – Securely packaged and dispatched using insulated or temperature-controlled packaging where required by the applicable transport and storage specification.

CJC-1295 Product Overview

Our CJC-1295 research-grade synthetic peptide is supplied for controlled scientific laboratory investigation, analytical method development, peptide characterisation, high-performance liquid chromatography assessment and mass-spectrometry workflows. The material comprises a defined modified 30-residue peptide structure containing four specified amino-acid substitutions and a C-terminal maleimidopropionyl-lysine modification.

The material is handled with a focus on batch traceability, documented quality control and consistent laboratory presentation. Product identity, chromatographic purity, net peptide content, molecular form, sequence, modified-residue integrity, counter-ion content, water content, residual solvents, bacterial endotoxin results and other analytical specifications should be confirmed using the applicable batch Certificate of Analysis. Chromatographic purity should not automatically be interpreted as equivalent to the total net peptide content of the vial.

For the majority of routine laboratory investigations, the Regular CJC-1295 specification remains highly suitable. The premium black-and-gold ULTIMATE CJC-1295 option provides an additional preparative high-performance liquid chromatography purification stage and a more stringent bacterial endotoxin and lipopolysaccharide testing specification for scientific projects requiring enhanced quality-control parameters.
