Anti-C1R Antibody

C1R is the catalytic serine protease subunit of the C1 complex that initiates the classical complement pathway, autoactivating on assembly with C1q and C1s before cleaving C1s to drive downstream effector responses. This rabbit polyclonal antibody from Antibodies.com is supplied as 100 µl of unconjugated antiserum and validated for Western blot and immunofluorescence on human and mouse samples. The polyclonal format recognizes multiple epitopes on the C1R heavy chain, supporting robust signal across cell lysates, tissue sections, and fixed preparations. Useful in studies of complement activation, innate immunity, inflammation, and autoimmune disease models. Aliquot on arrival, store refrigerated, and protect from light to preserve activity through repeated freeze-thaw cycles.
