Anti-P70S6K1 (phospho S424) Antibody

This rabbit polyclonal IgG reagent from Antibodies.com is raised against ribosomal protein S6 kinase beta-1 (RPS6KB1) and selectively recognizes the phosphorylated serine 424 site, a modification linked to kinase activation within the mTORC1 signaling cascade that controls protein synthesis and cell growth downstream of nutrient, growth factor, and stress cues.

Supplied as a 200 µl unconjugated liquid aliquot, the antibody is validated for Western blot (WB) detection of human samples. For long-term stability, store at -20 °C in small working aliquots to limit freeze-thaw cycles and preserve activity over the shelf life of the reagent. Researchers can pair this unconjugated primary with standard anti-rabbit secondary reagents and chemiluminescent or fluorescent detection systems for phospho-protein readouts in studies of mTOR signaling, translational control, and cell proliferation.
