Anti-p90RSK (Ab-348) Antibody

This rabbit polyclonal reagent from Antibodies.com targets p90RSK, a serine/threonine kinase that operates downstream of the MAPK/ERK signaling cascade and contributes to cell growth, survival, and transcriptional regulation.

Supplied as 100 µl of unconjugated polyclonal antiserum raised in rabbit, the reagent is validated for Western blot (WB) and immunofluorescence (IF) workflows and cross-reacts with p90RSK from human, mouse, and rat samples, supporting studies that compare kinase activation across species and tissue types.

Reagent characteristics:

• Host species: Rabbit
• Clonality: Polyclonal
• Conjugate: Unconjugated
• Reactivity: Human, Mouse, Rat
• Target: p90RSK
• Format: 100 µl vial
• Applications: WB, IF

Because p90RSK integrates mitogenic and stress signals through ERK-dependent phosphorylation, this antibody is commonly used to monitor pathway activity in cancer research, neurobiology, and signaling studies where changes in RSK phosphorylation are linked to proliferation or differentiation outcomes. The unconjugated format also allows researchers to couple the antibody to their preferred label for custom detection protocols.
