Anti-MAPK1 / MAPK3 Antibody

MAPK1 (ERK2) and MAPK3 (ERK1) are serine/threonine kinases that sit at the core of the Ras-Raf-MEK-ERK signaling cascade, transmitting extracellular mitogenic and stress cues into a diverse set of cellular responses including proliferation, differentiation, and survival. The Antibodies.com polyclonal reagent raised in rabbit targets conserved regions of both MAP kinases, supporting simultaneous detection of these related phospho-signaling partners in human, mouse, and rat samples. Validated for Western blot and immunohistochemistry workflows, the unconjugated antibody is supplied as a 100 µl aliquot and supports studies of growth factor signaling, oncogenic pathway activation, and tissue-level mapping of ERK1/2 expression patterns.
