Thermo Scientific™ Peptide Retention Standard

Thermo Scientific™ Peptide Retention Standard

Thermo Scientific Pierce Peptide Retention Standard is a mixture of five c-terminal amide decapeptides that provide reference elution profiles in reverse-phase HPLC.

Peptide Retention Standard allows accurate prediction of elution time for peptides of known amino acid composition up to 20 residues in length. The reference standard helps to predict the relative order of peptide elution within a complex mixture, simplifying identification of specified peptides and saving time in peptide purification. By testing the standard frequently throughout the lifetime of a column, it is possible to monitor performance characteristics such as efficiency, selectivity, and resolution during column aging. The standard can also be used to evaluate different reverse phase supports of varying n-alkyl chain lengths and ligand density, as well as columns from different manufacturers.
