S6K1抗体;S6K1 Antibody—艾普蒂 新品

The S6K1 antibody is a crucial tool in studying the mechanistic target of rapamycin (mTOR) signaling pathway, which regulates cell growth, proliferation, and metabolism. S6K1 (ribosomal protein S6 kinase beta-1), a serine/threonine kinase, is activated via phosphorylation by mTOR complex 1 (mTORC1) in response to nutrients, growth factors, and cellular energy status. It plays a central role in protein synthesis by phosphorylating ribosomal protein S6 and other substrates involved in mRNA translation. Researchers use S6K1 antibodies to detect endogenous protein levels, phosphorylation status (e.g., at Thr389 or Thr421/Ser424 sites), and activation dynamics in diverse biological contexts, including cancer, metabolic disorders, and aging. These antibodies are widely applied in techniques like Western blotting, immunofluorescence, and immunohistochemistry to investigate mTOR pathway activity, drug responses (e.g., rapamycin sensitivity), or disease-associated signaling alterations. Commercial S6K1 antibodies are typically validated for specificity across human, mouse, and rat samples, with phospho-specific versions distinguishing activated isoforms. Proper controls, such as knockout cell lines or phosphatase treatments, are essential to confirm antibody reliability in experimental setups.
