Anti-Connexin 37 Antibody

Raised in rabbit and purified by affinity chromatography, this polyclonal IgG reagent from Antibodies.com targets the gap-junction protein Connexin 37 (GJA4/Cx37), a 37 kDa channel subunit widely used as a cardiomyocyte and endothelial marker. The unconjugated antibody is supplied as a 50 µl liquid at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol, with a recommended storage temperature of -20 °C for long-term stability. It has been validated for Western blotting and immunohistochemistry on human, mouse and rat samples, where it recognises endogenous levels of Connexin 37 and is commonly applied to heart and vascular tissue sections. The host species is rabbit, the clonality is polyclonal, the isotype is IgG, and no carrier protein or secondary conjugate is attached, leaving the reagent suitable for downstream labelling with HRP, biotin or fluorophores of the user's choice. Each vial ships in a ready-to-use formulation that minimises freeze–thaw cycles and supports reproducible band detection around the predicted molecular weight of the target.
