Custom Peptide Library Synthesis Service
Peptide library are a powerful tool for drug design, protein-protein interactions, and other biochemical as well as pharmaceutical
applications. Crefu Peptides can offer below types peptide library:
Overlapping Peptide Library: Individual peptides can be divided in to several fragments that overlap. The resulting overlapping
peptide libraries can then be used for processes including continuous and linear epitope mapping.
Truncation Peptide Library: Peptides can be cleaved systematically into small fragments. The library of truncated peptides
could then be used to predict the minimum length amino acid that could be used to achieve optimal epitope activity.
Alanine Peptide Scanning Library: Each amino acid is substituted individually and systematically for alanine. Alanine scanning
allows the easy identification of the specific amino acids that are responsible for the conformation, activity, and function of
a protein.
Random Peptide Library: Selected positions are substituted with all 20 natural amino acids simultaneously, which
might increase peptide activity.
Scrambled Peptide Library: These libraries are designed using variations of the original sequence of a peptide. The resulting
peptides are used generally as negative controls to show that a specific sequence is critical to the protein function or activity.
It is also a random screening tool used to find new leads.
Positional Peptide Library: Selected sites or regions within a peptide sequence are replaced systematically with other amino
acids. These libraries facilitate the identification of the positions and regions that are responsible for specific activities or effects.
