Custom Peptide Libraries
Peptide libraries have become a commanding asset in the fast-growing field of proteomics and its related subfields including drug discovery, GPCR ligand screening, protein-protein interaction, functional proteome, nucleic acid binding, enzyme substrate or inhibitor screening, antigen and epitope screening, discovery of signal molecules, peptide/protein cross talking, etc.

GenScript has developed a rapid high-throughput parallel peptide synthesis platform equipped with six powerful peptide library generation protocols. They can be efficiently used in epitope mapping and sequence optimization.

Combinatorial peptide libraries and HTS compound arrays have become key players in drug discovery. These libraries can be used to screen highly active compounds such as antigenic peptides, receptor ligands, antimicrobial compounds, and enzyme inhibitors. Some of the applications of peptide screening tools are as follows:

  1. Epitope mapping studies.
  2. Vaccine research.
  3. High-throughput protein-protein interaction analysis.
  4. Customized peptide microarray production.
  5. Kinase assays.
GenScript has developed six powerful screening tools for generating peptide libraries. They are overlapping peptide library, alanine scanning library, truncation library, positional scanning library, random library, and scrambled library which are necessary tools in epitope identification and sequence optimization for structure-function studies.


Key Features:

  • Optimized Chemistries: GenScript peptide library synthesis uses optimized chemistries to ensure consistent quality, purity, and quantity batch-to-batch and within each batch.
  • No Cross-Contamination: Peptides are directly lyophilized in the wells of 96-well plates.
  • Comprehensive Modifications: Our modification service includes labeling, the incorporation of unnatural amino acids, and peptide cyclization with disulfide bridges.
  • Ready-to-Use Format: GenScript delivers peptide libraries in 96-well plates.
  • Stringent Quality Control: GenScript provides MS and HPLC validation data for each peptide.
