Anti-Kv4.1 (N588) Antibody

This polyclonal antibody targets the Kv4.1 voltage-gated potassium channel, the pore-forming subunit that carries rapidly inactivating transient outward K+ currents in cardiac myocytes and specific neuronal populations. Raised in rabbit against the N588 epitope, the reagent is supplied by Antibodies.com as an unconjugated IgG preparation at 1 mg/ml in phosphate buffered saline (approximately pH 7.2) with 0.05% sodium azide as a preservative. The 100 µl vial supports Western blot and immunohistochemistry workflows on human and mouse samples, and should be refrigerated upon receipt to preserve activity over time. Researchers apply it to studies of cardiac action potential repolarization, neuronal firing patterns, and ion channel subunit expression in heart and brain tissue.
