Anti-RPS6KA1 Antibody

Raised in rabbit against the serine/threonine kinase RPS6KA1, also known as RSK1 or p90RSK, this unconjugated polyclonal antibody from Antibodies.com is validated for Western blot and immunohistochemistry on human-derived samples and supplied as 100 µl of polyclonal antiserum for research use only.

RPS6KA1 operates downstream of the MAPK/ERK cascade and phosphorylates substrates including CREB, ATF1, and histone H3, coupling growth-factor, mitogen, and stress cues to transcriptional regulation and protein synthesis. The reagent enables researchers to track endogenous kinase levels in cell lysates and tissue sections, supporting signal-transduction studies, cancer-biology investigations, and molecular cell-biology workflows where downstream ERK-pathway readouts are of interest.
