Is the request about chemical characterization or biological activity?
Do not treat an amount stated in international units as an interchangeable milligram value. Clarify the material specification and the desired measurement. A routine peptide content result does not by itself establish a biological activity claim.
Also listed as: Human growth hormone; Somatropin. Confirm the intended form from the specification.
Information to include
Provide the product specification, labelled units, formulation and any reference information available for scope review.
- Name the exact variant, including any depot or chain modification
- Lyophilized powder in the original sealed vial is preferred
- Protein-scale submissions require a feasibility review before acceptance
Method and reporting scope
Above roughly 5 kDa, including recombinant and glycosylated material. Outside the assumptions of a routine peptide panel; accepted only after a specific method and reference discussion.
Area purity by HPLC-DAD, identity against reference spectra, verifiable COA. Reference availability and sample suitability are confirmed before acceptance. Read the method and reporting information for the techniques in your quote.
Price, timing and submission
The starting panel is $299 CAD. Volume rates, optional fees and tax are shown separately. Standard peptide analysis typically takes 5-10 business days after receipt and acceptance; other scopes are confirmed in the quote.
Wait for the quantity and mailing instructions before shipping. A report describes the sample tested. Testing one vial does not characterize every unit in a batch.
