Japanese company invests $3 million in Madison-based Semba Biosciences

Semba Biosciences, a Madison company that makes purifying equipment used by life sciences companies, is getting a $3 million investment from Tosoh Bioscience, part of a Japanese conglomerate, in a move that’s expected to lead to Tosoh’s eventual purchase of Semba.

Founded in 2005, Semba’s Octave Chromatography System has been used mainly for research purposes.

A new version of Octave that drew Tosoh’s investment will process and purify biological products being developed into drugs. It focuses on monoclonal antibodies, the foundation of many of the drugs currently being tested as potential cancer fighters and vaccines.
