Peptide/Protein Library Services for Phosphorylation Research


Creative BioMart provides comprehensive peptide/protein library services to accelerate kinase/phosphatase biology research and pharmaceutical development. We offer our expertise and extensive hands-on experience in the design and construction of peptide/protein libraries to fully meet the specific needs of our customers.


A peptide library is a large collection of peptides with systematic combination of amino acids. Protein libraries, on the other hand, contain a great number of proteins composed of designed backbone fragment or secondary structure modules. Peptide/protein libraries have been widely used as a powerful tool in biological research and drug development, providing a rapid and cost-effective solution for a wide range of applications.

Kinases and phosphatases are enzymes that catalyze the phosphorylation and dephosphorylation process, respectively. They play a significant role in a vast variety of cellular processes, such as gene transcription and translation, cell cycle, cell movement, protein-protein interactions, and metabolism. Abnormal phosphorylation is a cause or consequence of many diseases, making kinases/phosphatases a major class of drug targets for pharmaceutical industry. Various peptide/protein libraries have been successfully developed for identifying and screening substrates of kinases/phosphatases, potential phosphorylation targets, and hit compounds.
