Yeast Surface Display is used for the expression and subsequent screening of desired proteins and peptides in the field of antibody discovery and development. Current techniques involved in separation are tedious and require multiple enrichment steps as well as individual labeling for each separation step to achieve the desired protein with sufficient purity.  CQT’s MagDots that target biotinylated proteins allows for rapid and effective enrichment of antigen-binding clones in an open or column based magnetic separation system.
