How to Read a Thymosin Alpha-1 Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For Thymosin Alpha-1, the informative checks are not the same as for a generic short peptide.
Overview
Check the weight near 3108 and that its end-cap (acetyl group) is present.
What Thymosin Alpha-1 actually is
A 28-part peptide the thymus gland makes naturally, with one of the deepest research records of any immune peptide. Studied for how it helps T-cells mature and how the immune system responds to infection. The clinical version is called Zadaxin.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for Thymosin Alpha-1
What to check on the COA
Confirm the mass near 3108 Da and that the N-terminal acetyl group is present (an unacetylated impurity sits 42 Da lighter). Check peptide content separately from purity.
Unacetylated (-42 Da) and deamidated related substances.

Every batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity). Enter a lot number to pull the COA for the exact vial in front of you.
What Thymosin Alpha-1 is studied for
Studied for a role in the maturation and function of T-cells in immune research models.
Examined around innate immune signalling pathways, including Toll-like-receptor involvement, in preclinical work.
Investigated in models of immune response to infection and as a research adjuvant.
Summarizes published preclinical literature. Provided for research reference only; not a claim of efficacy or a description of human use.
