Anti-C4BPB Antibody

Distributed by Antibodies.com, this rabbit polyclonal antibody specifically recognizes Complement Component 4 Binding Protein Beta, a key regulator within the classical complement cascade. The unconjugated formulation supports flexible labelling strategies in custom detection workflows, and reactivity is confirmed against human antigens. Validated uses span Western blot, immunohistochemistry, and immunofluorescence, accommodating experimental approaches such as tissue-section imaging, lysate-based protein detection, and subcellular localization studies. C4BPB (also called C4bp-beta) is the smaller subunit of the C4b-binding protein complex, primarily expressed by hepatocytes, where it contributes to downregulating complement activation on host cell surfaces. Research groups in complement biology, innate immunity, autoimmune disease modeling, and hepatic protein expression routinely incorporate this reagent into their studies. The product is supplied at 1 mg/ml in PBS with 0.1% sodium azide as a preservative and 50% glycerol as a stabilant, packaged as a 50 µl vial for research use only.
