1. Peptide Library Services and Their Numerous Applications
A peptide library technique helps in studying structural and functional features of a protein.
The library service is a combination of peptides having a sequence or chain of amino
acids. The library is a great tool for drug designs, preparation and applications of
numerous proteins.
The peptide library service has wide applications in target validation, epitope mapping, and
vaccine development. The library services support a comprehensive and cost-effective
solution for various biological screening purposes. Furthermore, peptide libraries are
applied in biochemical studies of enzyme substrates, ligands or inhibitors.
Peptide synthesis companies follow numerous library methods for synthesis of variety of
products. These include custom, cosmetic, catalog and GMP peptides.
All the above four types of peptides have commercial usages besides applications in
formulation studies, research and development. A synthesized peptide drug is
administered to a person when it fails to naturally produce desired protein in the body.
Also, the products have diagnostic usages like checking blood pressure and clotting level
in humans.
• If you want to study about enzyme substrate reactions, proteases and collect further
information on cell signaling, the synthetic peptides become your first preference.
• The homologous synthetic peptides support to study the cell biology, receptor
binding and substrate recognition specificity of a newly found enzyme in the body.
• Synthetic peptides have much similarity with naturally occurring peptides and are
used as drugs against cancer and other major diseases.

2. • synthetic peptides are also preferred as standard reagents in mass spectrometry
based applications.
You can create a customized peptide library to meet your specific requirements with a
suitable design. Consider some of the peptide library designs described below.
• Overlapping Library: allows in scanning primary sequencing of proteins for
continuous linear epitopes mapping. The library is also ideal for T-cell epitope
identification. You can define the library generation process based on peptide length
and the degree of overlapping.
• Truncated Library: is designed with systematic cleavage of peptides to small
fragments to find amino acid with minimum length that supports a specific
functionality.
• Alanine Library: An Alanine or smallest natural amino acid is used to replace
residue of the original peptide. It allows easy identification of specific amino acids
responsible for conformation, activity, and function of a protein.
• Random Library: helps to check out the increased peptide activity by substituting
some select amino acid residues.
• Scrambled Library: is designed using the variations in original sequence or
composition of specific amino acid. The resulting peptide acts as a negative control
for a protein with critical activity.
• Positional Library: is produced with systematic replacement of amino acids
residues. The library facilitates identification of positions and areas responsible for
specific activities.
You can select a credible peptide library producer with state-of-the-art manufacturing
facilities, equipments and methods for your desired products.
