Human Complement Component 1,R Subcomponent (C1r) ELISA Kit

From Assay Genie, this quantitative in vitro ELISA kit measures human Complement Component 1, r subcomponent (C1r) in research specimens. C1r is a calcium-dependent serine protease that initiates the classical complement cascade: once C1q engages antibody-antigen complexes, C1r autoactivates and subsequently cleaves C1s, propagating downstream activation that drives inflammation, opsonization, and membrane-attack-complex assembly. Investigators studying autoimmune disease, hereditary angioedema, immune complex disorders, and complement-deficiency biology rely on C1r measurements to characterize pathway activity in their experimental systems. The kit supplies microplate strips, calibrated recombinant standards, biotinylated detection reagent, and substrate sufficient for 96 assays, run on a standard absorbance plate reader. All reagents are validated for human-sample workflows and supplied ready to use. Each production lot is QC-tested for inter-assay consistency. Intended for research use only; not for clinical diagnostic procedures.
