What are the raw materials, catalogue peptides and synthetic peptides, and what are the differences?

What is the purity of the peptide?

The purity refers to the content of modified peptides target polypeptide is detected by HPLC at a wavelength of 214nm (214nm wavelength is absorbed the peptide chain), not UV spectrophotometer salts and residual water. In general, the purified modified peptide contains impurities which are mostly modified sequences, such as a deletion sequence (a target sequence in which one or more amino acid residues are deleted), a truncation sequence (a sequence generated in a capping process). Deprotection of incomplete sequences (produced throughout the synthesis process or the final cleavage process).

Synthetic peptide (C ustom peptide synthesis)?

APIs ( APIs , active pharmaceutical ingredients) are pharmaceutically active ingredients in medicine, such as glucagon-like peptide - 1   ( G lucagon-likepeptide1,   GLP-1), Secretin (Secretin) and the like.
