American Made Peptides High-purity Lab-grade Peptides
Asymchem: Leading Cdmo For International Pharma Firms After synthesis and filtration, peptides are usually lyophilized (freeze-dried) as salts. One of the most typical counterion is trifluoroacetate (TFA) from the HPLC purification solvents, though some peptides are supplied as acetate or hydrochloride salts. These counterions aren't "impurities" in the HPLC feeling-- they don't show up as different tops-- yet they do contribute to the overall mass of the powder. For a 10-r
