Gemini Biosystems

GeminiBio is a private, commercial-stage life science tools and bioprocess supplier that provides critical raw materials used in biopharmaceutical, cell therapy, and gene therapy research, development, and manufacturing. Founded in 1985 and based in West Sacramento, California, the company sells human AB serum, fetal bovine serum, custom media, buffers, high-purity water, and other process liquids used from research through commercial production. GeminiBio operates cGMP manufacturing facilities and positions itself as a workflow partner for customers developing advanced therapies, including cell therapy, AAV, mRNA, and monoclonal antibody products. The company is backed by healthcare private equity firm BelHealth Investment Partners and has expanded both its manufacturing footprint and product portfolio in recent years. GeminiBio is not a therapeutic drug developer; rather, it is a commercial supplier enabling biomanufacturing and cell culture workflows.
