Anti-C1R Antibody

This polyclonal reagent from Antibodies.com targets complement component C1r, the serine protease subunit that activates C1s within the C1q-C1r-C1s initiation complex of the classical complement cascade. Raised in rabbit, the antibody is supplied unconjugated at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol, packaged as a 100 µl aliquot suitable for western blot, immunohistochemistry, and immunofluorescence workflows. Cross-reactivity has been validated against human and mouse samples, supporting studies of innate immune activation, autoimmune disease models, and complement-mediated tissue injury where C1r expression is being investigated at the protein level. The glycerol-containing formulation provides freeze-thaw protection for routine bench use, and the azide concentration allows short-term handling at room temperature without microbial contamination. Researchers studying lectin pathway crosstalk, classical pathway regulation, or hereditary C1r deficiency will find this antibody useful as a detection reagent across fixed and frozen tissue sections, as well as cell and tissue lysates for western blot analysis.
