Alpha Lifetech Inc. can provide high-quality peptide synthesis and related services to our clients.  


Truncation Peptide Library


Truncated libraries allow researchers to determine the shortest length of a peptide that is required for epitope activity. The original peptide sequence is systematically truncated by different monomeric units, and each peptide produced by this method can then be tested. Long peptides can be used in conjunction with alanine scanning libraries. Truncation library screening allows the identification of peptides with enhanced proteolytic stability. It can serve as a tool to investigate the extent to which peptide small molecules undergo metabolic degradation, which is a major consideration in bringing small molecules to the market.
