Anti-C4BPB Antibody

Raised in rabbit and affinity-purified against a recombinant human C4BPB immunogen, this polyclonal reagent from Antibodies.com is supplied as an unconjugated, ready-to-use primary antibody validated for Western blot (WB) and immunofluorescence (IF) workflows. Each vial contains 50 µl of antibody at 1.0 mg/mL, formulated in phosphate buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4, with 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as a cryoprotectant for typical –20 °C storage. The host species is rabbit, the clonality is polyclonal, and the conjugate is unconjugated, allowing flexible labelling with secondary reagents of the user's choice. Reactivity has been confirmed against human samples, with the antibody detecting endogenous levels of the total C4b-binding protein beta chain (C4BPB) — a complement-regulatory subunit. Published validation data from Antibodies.com includes immunofluorescence images of HeLa cells, where the antibody produces a specific staining pattern visualised alongside DAPI nuclear counterstain, supporting its use in cell-based localisation studies as well as standard WB membranes. The product is intended for research use only and is not for diagnostic or therapeutic applications.
