Anti-MEK Kinase-3 Antibody

The primary polyclonal antibody from Antibodies.com targets MEK Kinase-3 (MAP3K3), a serine/threonine kinase within the mitogen-activated protein kinase kinase kinase family that drives inflammation and cellular stress signaling cascades. Supplied as 100 µl of unconjugated rabbit antiserum, the reagent is validated for Western blot, immunohistochemistry, and immunofluorescence workflows on human and mouse specimens. Researchers studying NF-κB activation, cytokine responses, or MAPK pathway crosstalk frequently rely on polyclonal capture of endogenous MAP3K3 to localize its activity in tissue sections and cell lysates without the constraints of a labeled secondary conjugate. The preparation is intended for research use only and should be aliquoted upon arrival to limit freeze-thaw cycles; for long-term storage, keep the vial frozen and protect from light. Each lot supports applications spanning membrane-based immunoblotting, fixed-tissue staining, and subcellular localization studies.
