About CHO Plus, Inc.

CHO Plus was founded in 2014 with the mission of increasing the productivity of cells used for manufacturing life-saving therapeutic proteins for treating human disease (such as antibodies for the treatment of cancer). CHO Plus has developed patented cell engineering technology to increase the amount of protein-producing “machinery” (e.g. endoplasmic reticulum) within each cell. Current studies demonstrate productivity increases of up to 10-fold for therapeutic antibodies. This could lower pharmaceutical industry production costs by billions of dollars each year in aggregate, if widely adopted. In 2021 CHO Plus further applied its technology toward increasing productivity of cells used for production of virus vectors (such as AAV) for gene therapy. Current studies demonstrate cell productivity increases of over 15-fold for AAV, with up to 55% full capsids.

CHO Plus is located at the Johnson & Johnson Innovation – JLABS incubator in South San Francisco, CA.
