Anti-P90RSK (phospho T348) Antibody - Identical to Abcam (ab194743)

This rabbit polyclonal antibody from Antibodies.com specifically detects P90RSK phosphorylated at threonine 348, an ERK1/2-driven modification in the N-terminal activation loop of the kinase. Supplied as an unconjugated IgG in 100 µl, the reagent is validated for Western blot, immunohistochemistry, and immunofluorescence.

Phosphorylation at T348 is a widely used readout of MAPK/ERK pathway engagement in growth factor, mitogen, and cellular stress studies, and is applied in tumor biology, neuronal signaling, and metabolic disease research to monitor downstream kinase activity. Reactivity covers human, mouse, and rat samples, enabling comparative work between cultured cells, primary tissue lysates, and animal models.

For best results, aliquot the vial upon first thaw to limit repeated freeze-thaw cycles, store working dilutions at 4 °C, and keep the stock frozen at -20 °C protected from light. The product is supplied for research use only and is not cleared for diagnostic or therapeutic applications.
