In prominent research fields such as immunotherapy, vaccine development, drug discovery, and proteomics, target screening is frequently carried out using peptide libraries, which are systematic combinations of various peptides.

To assure the success of any study, GenScript provides complete AccuPep QC services, such as TFA Removal, Solubility Testing, Endotoxin Control & Analysis, and others, using their PepHTS™ platform.
