Anti-p90RSK (Ab-348) Antibody

Offered by Antibodies.com as a research-grade primary antibody, this rabbit polyclonal reagent targets the p90RSK protein at the Ab-348 epitope and is supplied at a concentration of 1.0 mg/mL in a 50 µl volume. The antibody was raised against a synthetic peptide corresponding to amino acids 346–350 (S-R-T-P-R) of mouse p90RSK, and it specifically recognises endogenous levels of total p90RSK, with a predicted molecular weight of approximately 90 kDa. It is unconjugated and recommended for Western blotting (typically 1:500–1:1000) and immunofluorescence staining, including ICC/IF applications, where dilutions of 1:100–1:200 are suggested. The reagent has been validated for reactivity against human, mouse, and rat samples and is purified by affinity chromatography using the epitope-specific peptide following immunisation with KLH-conjugated immunogen. For handling, the product is shipped at 4 °C in phosphate-buffered saline (pH 7.4, without Mg²⁺ and Ca²⁺) containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol; upon receipt it should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve performance. Intended strictly for research use, this Antibodies.com polyclonal provides a reliable tool for studying RSK-family kinase signalling in cell and tissue lysates across multiple species.
