Anti-MAPK13 Antibody

Raised in rabbit against the MAPK13 (p38 delta / SAPK4) stress-activated kinase, this polyclonal antibody from Antibodies.com is supplied as 100 µl of unconjugated reagent for Western blot and immunohistochemistry work on human, mouse, and rat samples.

MAPK13 is the p38δ member of the p38 MAPK family and is activated downstream of inflammatory cytokines and cellular stress, with documented roles in myogenic differentiation, cardiac stress responses, and cartilage biology. The polyclonal format presents antibodies against multiple epitopes along the protein, which is helpful when probing across species or when a single monoclonal may miss particular isoforms or post-translational modifications.

Validated applications include Western blot for detecting endogenous MAPK13 in cell and tissue lysates, and immunohistochemistry for localizing expression in fixed tissue sections. The unconjugated format lets researchers pair the antibody with their preferred reporter system, including HRP-based chromogenic substrates, fluorescent secondaries, or biotin-streptavidin amplification. Aliquot on receipt and store at -20°C in working volumes to limit freeze-thaw cycles; protect from light if a fluorescent conjugate is later introduced.

Reported reactivity covers Human, Mouse, and Rat, supporting the most common mammalian model systems. Each vial is intended for research use only and is not validated for diagnostic or therapeutic applications.
