Affinity separation: divide and conquer the proteome

A major challenge in protein target discovery and validation is how to specifically dissect complex protein mixtures and measure trace targets. Immunoaffinity-based protein capture, separation and detection have proven to be one of the most effective approaches. Avian IgY antibody microbeads (Seppro™), representing a type of novel and specific protein sorbent, have several distinct advantages over IgG. Their utility and applications are compared...
