Anti-P90RSK (phospho S352) Antibody

Phospho-specific detection of activated P90RSK at the serine 352 autophosphorylation site, raised in rabbit as an affinity-purified polyclonal IgG and supplied unconjugated in a 200 µl vial. P90RSK (also known as RSK1 or RPS6KA1) operates downstream of the ERK1/2 MAPK cascade, with phosphorylation at S352 occurring as part of its sequential activation mechanism. Distributed by Antibodies.com, the reagent is validated for Western Blot analysis of the human target, enabling researchers to monitor pathway activity in cell lysates prepared from stimulated or treated samples. The polyclonal backbone supports recognition of multiple epitopes flanking the phospho-S352 residue, which is helpful when probing kinase activation kinetics downstream of growth factor, genotoxic stress, or oncogenic signaling inputs. For long-term stability, store at -20 °C and avoid repeated freeze-thaw cycles by aliquoting upon first use.
