What this certificate shows
Purity 99.74 %. Reversed-phase HPLC separates the contents of the vial by how they interact with the column, and a UV detector measures each peak. 99.74 % of the detected material in lot BK-TB-5 is the target peptide, TB-500 10 mg; the remaining 0.26 % is made up of closely related sequences and synthesis by-products. Purity describes what the peptide portion is, not how much powder is in the vial.
How each figure is measured, and the limits a lot must meet before release, are set out in our testing methods. For in-vitro laboratory research only.
