ProteomeLab IgY-12 partitioning chemistries from Beckman Coulter Inc. (Fullerton,CA) increase throughput capacity of the company’s columns. Each column now partitions twice as much plasma or serum per cycle as the original version, up to 250 μl per cycle. The capacity of ProteomeLab IgY-HSA spin columns has also been doubled, to 40 μl plasma or serum per cycle. Based on avian-generated antibodies bound to inert microbeads, ProteomeLab IgY-12 liquid chromatography and spin columns selectively partition 12 highly abundant proteins — up to 96% of the protein mass — from human/primate serum or plasma. IgY chemistries offer clean capture and a broad antigen-binding host range because of the evolutionary distance between chickens and mammals. Beckman Coulter, Inc.800-742-2345www.beckmancoulter.com
