Carbonic anhydrase IX
CAIX, CA-IX, Carbonic anhydrase 9, CA9
Detects human carbonic anhydrase 9. This non-therapeutic antibody uses the same variable region sequence as the therapeutic antibody girentuximab.
This recombinant protein was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
RUO girentuximab binds to the extracellular proteoglycan (PG)-like domain, which is unique to CA IX compared to other isoforms and lies adjacent to the catalytic domain. In addition to therapy, girentuximab has also been utilized as an imaging agent.
