Recombinant Proteins

Our portfolio is expanding and now includes over 2,000 bioactive human, mouse, and rat recombinant proteins developed in-house. These proteins are used for bioassays in a number of research areas including immunology, neuroscience, stem cell research, and cancer research, as well as cell and gene therapy applications. Recombinant proteins produced under Current Good Manufacturing Practices (cGMP) can be used for expansion, polarization, and differentiation of cells, and ex vivo cell bioprocessing applications.
