Anti-KCNJ4 Antibody

Targeting KCNJ4 (Kir2.3), an inward rectifier potassium channel of the Kir2.x family, this Antibodies.com reagent is a rabbit polyclonal antibody supplied as 200 µl of unconjugated IgG antisera and validated for western blot in mouse and rat samples.

KCNJ4 contributes to the maintenance of resting membrane potential and potassium ion conductance in excitable cells, making it a frequent subject in neuroscience and cardiac electrophysiology research. Investigators studying channelopathies, neuronal firing patterns, or cardiac repolarization use this reagent to detect endogenous KCNJ4 expression in tissue homogenates and cultured cell lysates.

The polyclonal antibody pool offers epitope diversity, supporting reproducible recognition of the target across multiple binding sites in immunoblotting workflows. For long-term performance, store refrigerated and protect from light; aliquot the 200 µl vial after first use to limit freeze-thaw cycles and preserve activity over the reagent's shelf life.
