CaptureSelect™ C1-inhibitor Affinity Matrix is intended for the purification of human C1 esterase inhibitor from recombinant as well as plasma/serum sources.

• Efficient purification of C1 esterase inhibitor with high yields and retained activity
• Excellent scalability
• Non-animal derived

CaptureSelect C1-inhibitor Affinity Matrix binds human C1 esterase inhibitor from recombinant and plasma/serum sources. C1 esterase inhibitor is a protease inhibitor belonging to the serpin superfamily that inhibits the complement system to prevent spontaneous activation. The high selectivity and yields obtained using C1-inhibitor Affinity Matrix enable a robust and efficient purification process with excellent purity in one step.

Free of animal components
Thermo Fisher Scientific CaptureSelect products are affinity ligands created by a proprietary technology based on camelid-derived single-domain antibody fragments. The ligand is a 13-kDa single-domain fragment that comprises the 3 CDRs that form the antigen binding domain and is efficiently produced by the yeast Saccharomyces cerevisiae in a production process free of animal components.
