Princeton, NJ, April 9, 2007 — today announced the addition of a state-of-the-art antibody purification system for monoclonal and polyclonal antibodies, offering customers the highest quality antibody production through greater efficiency, reliability, and reproducibility for antibody purification.

The automated, high-performance liquid chromatography equipment will be used for the purification of monoclonal and polyclonal antibodies from serum, ascites, and cell culture supernatant.
