Human/Mouse/Rat Phospho-MKK3 (S189) PharmaGenie ELISA Kit (SBRS1896)

The Phospho-MKK3 (S189) PharmaGenie reagent from Assay Genie is a phosphorylation-site-specific ELISA built around a capture antibody directed against the activating Ser189 residue on MKK3 (MAP2K3). Because MKK3 sits upstream of p38 MAPK, researchers studying inflammatory cascades, osmotic shock, and cytokine signalling use this kit to quantify pathway activation in cell lysates and tissue lysates. Cross-reactivity with mouse and rat orthologues alongside human samples enables translational comparisons across species within the same study.

Each Assay Genie kit supplies a precoated microplate together with detection antibody, lyophilised standards, buffers, and TMB substrate sufficient for 96 assays. Reagents are shipped on cold packs and should be stored at -20 degrees C between uses to preserve antibody activity across multiple freeze-thaw cycles. Intended for in vitro research use only, the kit supports pathway analysis in studies of cancer, neurodegeneration, and immune cell biology where phospho-MKK3 status serves as a read-out of upstream stress-kinase activity.
