In biomedical research and biomanufacturing, the purity of reagents directly impacts the reliability of experimental outcomes and the safety of downstream therapeutic products. Endotoxins are notorious contaminants in protein preparations. Even trace amounts of endotoxin in recombinant proteins can trigger potent immune responses, distort results, and compromise patient safety, especially in sensitive applications such as immunology, cell and gene therapy, and vaccine production. Sino Biological has addressed this urgent need with the launch of ProPure™, an advanced line of endotoxin-free recombinant proteins.
