Anti-ERK1 Antibody

Generated against the ERK1 (MAPK3) protein, this Rabbit polyclonal antibody from Antibodies.com recognizes a 44 kDa serine/threonine kinase that sits within the canonical MAPK/ERK signaling cascade. The unconjugated reagent is supplied at 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol, and each vial contains 100 µl of ready-to-use stock.

Validated for western blot and immunohistochemistry workflows, the antibody has been reactivity-tested against Human, Mouse, and Rat samples. As a polyclonal reagent raised in Rabbit, it offers epitope diversity across the ERK1 target, supporting detection studies tied to cell proliferation, differentiation, and cellular stress response research.

Storage at -20 °C in single-use aliquots limits freeze-thaw cycles, with the sodium azide preventing microbial contamination. The unconjugated format allows flexible pairing with secondary antibodies of the researcher's choice for chromogenic or fluorescent detection readouts.
