Every peptide, protein and blend we have tested, from our own testing records. Purity, quantity and identity on one vial from $250, with endotoxin, sterility and heavy metals at the higher levels. Compounds with a data sheet are linked; the rest are tested on the same methods and can be ordered the same way.
Email [email protected] with the compound name and sequence and we will tell you whether we have a method for it. Most single peptides and small molecules can be run on the standard HPLC-UV method with a reference standard; blends and unusual compounds may need a method check first.
