Human C1R/Complement Component C1r quantitates human C1R/Complement Component C1r in serum, plasma, supernatant. The assay will exclusively recognize both natural and recombinant human C1R/Complement Component C1r.
C1 component of human complement is a complex of three glycoproteins: C1q, C1r and C1s. C1r has a molecular weight of 83,000 and is present in plasma in an average concentration of 50 µg/mL, either as a complex with C1q and C1s or in the absence of C1q as a tetramer with C1s. The subcomponents of the C1 complex are responsible for the initiation of the classical pathway of complement activation.
