Protein & Peptide Analysis

Why use a peptide library?

Dipeptide and tripeptide libraries can be systematically constructed to contain almost all possible combinations of the 20 common amino acids. 1

Peptide libraries can be used to study ligand-receptor interactions, epitope mapping, vaccine development, and drug screening. 2

Dipeptide libraries, in particular, have been prepared to study a broad range of physicochemical properties, making them especially useful to pharmaceutical companies as a potential source for novel drug structures. 3 Another advantage of dipeptide libraries is their simple structure, which eliminates the need for deconvolution in identifying novel structures and allows the peptides to be taken up by bacterial and eukaryotic cell membranes for direct interaction with target proteins in vivo. 3-6

Dipeptide Library

The table below presents all dipeptides possibilities. Dipeptides containing N-terminal Glutamine or Glutamic acid are known to form pryoGlutamate (pGlu). The purity of the grey highlighted peptides is expressed as a sum of both products (pGlu formation can vary from 20% to 50%), which is >95% pure by analytical HPLC. Once dissolved in solutions, these dipeptides should be utilized fairly quickly. Empty boxes denote that the peptides are not available. Unless otherwise specified, all other peptides are >95%.
