Organized around stem-cell research, Primorigen Biosciences has been providing solutions for stem cell maintenance, proliferation, differentiation and large scale production. In August 2019, it was announced that the firm had been acquired by Nucleus Biologics - a younger and smaller firm. Primorigen products include Vitronectin XFâ¢, a recombinant human protein that offers a defined, xenobiotic-free substrate for pluripotent cell proliferation and differentiation; MesoTotalâ¢, a high efficiency, high yield hematopoietic stem cell differentiation medium; high quality monoclonal antibodies validated for stem cell characterization--including flow cytometry; human cytokines and growth factors, and others. Products in development include next-generation matrices and related technologies for stem cell expansion, differentiation and media reduction, cost-effective systems for consistent, simple industrial scale stem cell production, and HTS plates populated with stem cell derived phenotypes for screening environmental toxins and other compound. In addition, Primorigenâs proprietary Spot on Dots⢠frameless microarray platform provides a versatile, high-throughput substrate for building quantitative assays to detect proteins of interest. The platform offers greater speed and flexibility for antibody screening and assay development, and generates thousands of data points per experiment at a fraction of the costs of other systems, including ELISA. Primorigenâs low cost detection instrument and user-friendly PrimeAlyzer⢠software analyzes and reports back key data i
