Reference structure: Published ACE-083 is described as a dimeric fusion protein comprising human follistatin-291 joined to the constant-region fragment of human immunoglobulin G2. Confirm that the supplied protein matches the intended construct using the manufacturer's sequence and structural documentation.

The external identifiers and estimated molecular values do not establish the identity or measured mass of the supplied batch. Reconcile the original mass range with the manufacturer's confirmed sequence, glycosylation information, assembled protein form and analytical method before using it in calculations.

Premium ULTIMATE Laboratory Specification

ULTIMATE ACE-083

Additional chromatographic purification and more stringent endotoxin testing

The ULTIMATE ACE-083 option is intended for laboratories requiring additional preparative high-performance liquid chromatography purification and a more stringent bacterial endotoxin testing specification for lipopolysaccharides. Confirm the product-specific purification process, testing requirements and results in the documentation for the selected grade and batch. Any additional chromatographic processing must be appropriate to the supplied recombinant fusion protein.

Additional Purification

Review the documented additional preparative high-performance liquid chromatography stage and its suitability for the supplied fusion protein. Confirm the structural-quality assessment following purification.

More Stringent Endotoxin Testing

Confirm the analytical method, acceptance criteria and reported results against the product-specific ULTIMATE bacterial endotoxin specification.

Batch-Specific Assessment

Refer to the completed Certificate of Analysis for the identity, reported purity, endotoxin result and specification of the selected batch.

Regular or ULTIMATE?

Our Regular ACE-083 remains a suitable choice for routine laboratory work where its documented specification meets the requirements of the intended method. Select ULTIMATE where the additional purification stage and more stringent endotoxin specification are required by your laboratory procedure.

For research use only. The ULTIMATE designation does not, by itself, establish a numerical purity, an endotoxin limit or sterility. Confirm the relevant specification and results in the batch documentation. Neither grade is intended for human or animal use.

Recombinant Protein – Laboratory Specification

ACE-083 is supplied as a research-grade recombinant protein for controlled laboratory handling and analytical work. Confirm the protein construct, declared content and formulation against the manufacturer's specification. The catalogue description alone does not establish batch purity, structural integrity or performance in a particular laboratory method.

Formulation Process and Quality Assurance

Identity and analytical verification: Review the manufacturer's sequence documentation and analytical results for the actual protein supplied. Check the tests performed, the characteristics measured and the acceptance criteria applicable to the selected batch.

Purification and batch consistency: Confirm the documented purification process and the results supporting the stated composition and quality specification. Assess any claim of consistent performance against the relevant batch records and intended laboratory method.

Manufacturing information: The supplied description refers to manufacture in the United Kingdom, the United States or Germany without identifying a specific site. Refer to the batch-specific supplier records for the actual manufacturer, production location and applicable quality-control documentation.

Laboratory Handling and Preparation

Handling and preparation should be carried out by qualified personnel using appropriate laboratory procedures. Confirm the supplied physical form before preparation; the original description does not establish whether the product is a solution, lyophilised material or another presentation.

Where reconstitution or dilution is required, follow the manufacturer's instructions for the exact protein formulation and your laboratory's validated method. Confirm the appropriate buffer, concentration, handling conditions and storage requirements. No universal reconstitution medium is specified here.

The source description refers to sterile laboratory vials. Confirm any container or finished-product sterility claim against the relevant records; do not infer the sterility of the contents from the container description.

Follow the product-specific handling, storage and disposal instructions. Research Scientific does not provide guidance on use outside controlled research environments or advice on dosage, administration or use in humans or animals.

Batch Documentation and Delivery

Certificate of Analysis: Review the completed batch certificate for the tests performed, analytical methods, reported results and applicable specifications. Scan the code on the packaging, where provided, or contact Research Scientific to confirm which documentation is available for the selected batch.

Safety Data Sheet: Consult the current, product-specific Safety Data Sheet for information supporting laboratory risk assessment, safe handling, storage and disposal.

Supporting records: Match the manufacturer, product name, formulation, selected grade and batch number across the label and available documentation before relying on the records for laboratory quality assessment.

Tracked delivery: Securely packaged and dispatched in insulated packaging using a tracked delivery service. Follow the product's storage instructions upon receipt.
