Anti-GJA4 Antibody

Offered by Antibodies.com, this rabbit polyclonal reagent is raised against a recombinant human GJA4 immunogen and affinity-purified to deliver reliable detection of endogenous connexin-37 (Gap junction alpha-4 protein / Cx37) across multiple species. Supplied at 1.0 mg/mL in a 50 µL volume as an unconjugated polyclonal antibody, the product is validated for Western Blot (WB) and Immunohistochemistry (IHC) applications and shows strong reactivity with human, mouse, and rat samples. The formulation uses phosphate-buffered saline at pH 7.4 (without Mg²⁺ and Ca²⁺), containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol, which helps preserve antibody activity during routine handling. Shipping is performed at 4 °C, after which the vial should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided. The antibody is intended for research use only and is not validated for diagnostic or therapeutic purposes, making it well suited for laboratories exploring gap-junction biology, vascular connexin expression, or comparative studies of Cx37 in rodent and human tissues. With its polyclonal profile, broad species cross-reactivity, and dual-application validation, this Antibodies.com reagent provides a flexible option for western blotting of total GJA4 protein and immunohistochemical localization in tissue sections.
