Anti-GJA1 Antibody

Raised in rabbit and affinity-purified against a recombinant human GJA1 immunogen, this polyclonal reagent from Antibodies.com is supplied at 1.0 mg/mL in a 50 µL aliquot and is intended for the detection of endogenous connexin-43 (also known as Cx43, gap junction alpha-1 protein, or the 43 kDa gap junction heart protein). The antibody is unconjugated and is formulated in phosphate-buffered saline at pH 7.4 (150 mM NaCl) with 0.02% sodium azide and 50% glycerol, without Mg²⁺ or Ca²⁺. It is shipped at 4 °C and should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve performance. The host species is rabbit, the clonality is polyclonal, and the conjugate status is unconjugated, allowing flexible labelling in downstream assays. Validated applications include Western blotting (WB) and immunohistochemistry (IHC), and the reagent has been confirmed to react with human and mouse samples. Catalog number A38498 corresponds to the 50 µL pack size, and the product is offered for research use only and is not intended for diagnostic or therapeutic applications. With its combination of a robust polyclonal response and a defined buffer formulation, this reagent is well suited to studies of gap junction biology and connexin-43 expression in cell and tissue lysates.
