Abstract :

ProxiMAX’ randomization is the technology that lies behind Isogenica’s Colibra™ offering. It is a defined saturation mutagenesis process that delivers precision control of both identity and relative ratio of amino acids at specified locations within a protein/ antibody library. Thus unwanted amino acids such as cysteine and methionine can be eliminated from libraries because no constraints are imposed by the genetic code. Moreover, the process is non-degenerate, which means that encoding DNA libraries are as small as is physically possible. ProxiMAX relies on a process of saturation cycling comprising ligation, amplification and digestion for each cycle and is the science behind the commercial “Colibra™” technology. With achieved diversities of >99% (6 and 11 saturated codons) and the potential to generate libraries of up to 1014 components, we contest that ProxiMAX randomization is a vital tool in engineering antibody libraries of the highest quality. This presentation will examine the development of the ProxiMAX process and give examples of antibody libraries created to date.
