      Background InformationAlso known as dual specificity mitogen-activated protein kinase kinase 4, JNK-activating kinase 1, and MAP/ERK kinase 4 among other names, MKK4 is protein kinase that plays a critical role in the MAP kinase signal transduction pathway and in stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling. MKK4 is required for maintenance of peripheral lymphoid homeostasis, and is involved in stress response and apoptosis. It also acts as a metastasis suppressor in certain cancers, such as prostate and ovarian cancer.

      Product Usage Statements
      Quality AssuranceEvaluated by Western Blot in activated MKK4 (Cat. No. 14-377) alone, or with non phospho or phospho peptide.

      Western Blot Analysis: A 1:30,000 diluiton of this antibody detected phospho-MKK4 (Ser257/Thr261) in 500 ng of activated MKK4 recombinant protein. Peptide inhibition was observed with the addition of phospho peptides, but not with the addition of non-phospho peptides or antibody alone (500 ng of recombinant protein was loaded onto the SDS-PAGE gel. It is recommended for end-users to determine optimal antibody dilutions respective to the amount of test sample used.).
