Anti-C7 Antibody

Complement component 7 (C7) is a single-chain glycoprotein that joins the membrane attack complex during terminal complement activation, making it a useful marker for innate immune and inflammatory studies. This unconjugated polyclonal reagent from Antibodies.com is raised in rabbit and validated for Western blot and immunohistochemistry workflows, with reactivity confirmed against human, mouse, and rat samples.

The antibody is supplied as a 100 µl liquid aliquot at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant, supporting direct dilution into standard assay buffers. Short-term storage at 4°C suits working aliquots, while long-term stability is maintained by freezing at -20°C in single-use fractions to limit freeze-thaw cycles and preserve epitope recognition.

Researchers investigating complement-mediated lysis, autoimmune disease models, or tissue-level deposition studies will appreciate the cross-species reactivity and the unconjugated format, which permits flexible pairing with HRP, biotin, or fluorophore-conjugated secondary reagents for chromogenic or fluorescent detection.
