Human/Mouse/Rat MLK4 alpha Antibody Summary

Species Reactivity
Human, Mouse, Rat
Detects endogenous human, mouse, and rat MLK4 alpha. Because the peptide immunogen corresponds to a region at the C-terminus of MLK4 alpha absent in MLK4 beta, no reactivity with MLK4 beta is present.
Polyclonal Rabbit IgG
Antigen Affinity-purified
Human MLK4 alpha synthetic peptide (aa 560 - 570)
Accession # CAC84639
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.


Recommended Concentration
Western Blot
1 µg/mL
See below
5-15 µg/mL

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Data Examples

Immunohistochemistry MLK4 alpha  in Human Colon Cancer Tissue. View Larger

MLK4 alpha in Human Colon Cancer Tissue. MLK4a was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using 10 µg/mL Human/Mouse/Rat MLK4a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3435) overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained with the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue). Specific labeling was localized to microvilli of epithelial cells. Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Western Blot Detection of Human/Mouse/Rat MLK4 alpha  by Western Blot. View Larger

Detection of Human/Mouse/Rat MLK4 alpha by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line, Ramos human Burkitt's lymphoma cell line, A20 mouse B cell lymphoma cell line, CH-1 mouse B cell lymphoma cell line, Rat-2 rat embryonic fibroblast cell line, and L6 rat myoblast cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat MLK4a Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3435) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for MLK4a at approximately 62 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: MLK4 alpha

Mixed-lineage kinases (MLKs) function as mitogen-activated protein kinase kinase kinases (MAP3Ks), activating the p38 and JNK signaling cascades. The potential importance of MLK4’s role in cell regulation has been indicated by the finding of nine separate mlk4 point mutations in a recent sampling of colorectal cancers. MLK4 has two splice variants, with MLK4 alpha containing a different and shorter C-terminus than MLK4 beta.
