Protein Purification Reagents

Protein purification reagents are for use in isolating one or more proteins from a complex mixture, usually cells, tissues, or whole organisms. This process is vital for function and structure characterization, as well as identifying interactions of the protein of interest. Important during the many steps, the protein purification reagents assist with cell lysis, separating the soluble protein components from cell debris, and finally separating the protein of interest from product- and process-related impurities.
