Anti-P90RSK (phospho S352) Antibody

This polyclonal antibody specifically recognizes P90RSK (also known as RSK1 or RPS6KA1) when phosphorylated at serine 352, a regulatory site within the C-terminal kinase domain that becomes modified following ERK/MAPK pathway activation. The phospho-S352 mark serves as a useful readout for studying growth factor signaling, mitogenic responses, and downstream kinase activity in cellular research models.

Produced by Antibodies.com, the reagent is raised in rabbit and purified as IgG in an unconjugated format, supplied at 100 µl per vial. Validation has been performed for western blot (WB) applications using human samples, and the antibody is commonly deployed in studies of oncogenic signaling, cell cycle progression, and stress-activated kinase cascades.

Key product attributes include rabbit host species, polyclonal clonality, IgG isotype, and reactivity confirmed for human targets. The antibody is intended for research use only and should be handled under standard phospho-antibody storage conditions to retain epitope-specific binding activity across multiple experiments.
