Recombinant Proteins are routinely used for studies in cancer, angiogenesis, neuroscience, apoptosis, cell signaling, immunology and other research areas. Whether used separately or with our primary cells, antibodies, and ELISA kits, CAI recombinant proteins provide consistent quality and value to advance your research. The highly purified, filtered, sterile proteins are expressed in E. coli and lyophilized for a convenient, cost-effective aliquot that contains no carrier proteins or additives. They are sequence verified, endotoxin tested, lyophilized and assayed for biological activity. Bulk quantities are available upon request. The proteins are produced under stringent protocols, standards and documentation. Test results include protein concentration, lot-specific SDS-PAGE, endotoxin and bioactivity.
