Anti-MST-3 Antibody

MST-3 (also called STK24) is a serine/threonine kinase of the STE20 family that links stress signals to apoptosis and cytoskeletal remodeling. Antibodies.com offers a rabbit polyclonal reagent raised against this kinase for researchers who need a flexible detection tool across multiple model organisms.

Supplied as 100 µL of unconjugated antiserum, the antibody reacts with human, mouse, and rat MST-3, supporting comparative work in cell lines, primary cultures, and tissue lysates. Polyclonal recognition of multiple epitopes is particularly useful when studying post-translational processing, such as caspase-mediated cleavage during apoptosis, where antibody binding can otherwise be lost.

Validated uses include Western blot for protein-level quantification, immunohistochemistry for spatial localization in fixed tissue sections, and ELISA. For blots, the reagent pairs with standard anti-rabbit HRP or fluorescent secondaries on PVDF or nitrocellulose. For IHC, antigen retrieval and blocking conditions should be optimized to the specific sample type. Each vial should be stored refrigerated, aliquoted on first thaw, and protected from repeated freeze-thaw cycles to preserve titer.
