Positional Peptide Library Construction

Scientists at Alpha Lifetech Inc. continuously strive to produce high-quality random peptide libraries and related services to solve problems in scientific discovery.

 

Positional Peptide Library

 

Positional Peptide Library is an important tool for peptide sequence optimization. Amino acids of interest at a given position(s) are substituted with all other natural amino acids, one at a time. This allows the identification of amino acids that enhance peptide activity. (Num. 01: Original Sequence; Num. 02 - 03: Single Point Mutation; Num. 04, 05: Combinatorial 2-Positional Mutation; Num. 06, 07: Combinatorial 3-Positional Mutation)
