Description: This MRRBY monoclonal antibody recognizes human and mouse mammalian target of rapamycin (also known as mTOR, FRAP, RAFT) when phosphorylated on S2448. mTOR is a serine/threonine protein kinase that functions as an ATP and amino acid sensor as well as to balance nutrient availability with cell growth, proliferation, motility, survival, protein synthesis, and transcription. Activated mTOR increases production of enzymes necessary for glycolysis and controls the uptake of glucose and other nutrients. Increased glucose uptake and metabolism helps fulfill the energy needs for mTOR-driven cell growth and proliferation. When sufficient nutrients are available, mTOR transmits a positive signal to p70 S6 kinase and participates in the inactivation of the eIF4E inhibitor, 4E-BP1. mTOR is phosphorylated at S2448 via the PI3 kinase/Akt signaling pathway and is autophosphorylated at Ser2481. Due to its critical role in regulation of cell growth, survival, and metabolism, and because it is often abnormally regulated in tumors, mTOR is under investigation as a potential target for anti-cancer therapy.
Applications Reported: This MRRBY antibody has been reported for use in intracellular staining followed by flow cytometric analysis.
Applications Tested: This MRRBY antibody has been pre-titrated and tested by intracellular staining followed by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.5 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
Staining Protocol: All protocols work well for this monoclonal antibody. Use of Protocol A: Two-step protocol: intracellular (cytoplasmic) proteins allows for the greatest flexibility for detection of surface and intracellular (cytoplasmic) proteins. Use of Protocol B: One-step protocol: intracellular (nuclear) proteins is recommended for staining of transcription factors in conjunction with surface and phosphorylated intracellular (cytoplasmic) proteins. Protocol C: Two-step protocol: Fixation/Methanol allows for the greatest discrimination of phospho-specific signaling between unstimulated and stimulated samples, but with limitations on the ability to stain specific surface proteins (refer to "Clone Performance Following Fixation/Permeabilization" located in the Best Protocols Section under the Resources tab online). All Protocols can be found in the Flow Cytometry Protocols: "Staining Intracellular Antigens for Flow Cytometry Protocol" located in the Best Protocols Section under the Resources tab online.

Mammalian target of rapamycin (mTOR) is a serine/threonine kinase that plays a key role in cell growth, cell proliferation, and protein synthesis. mTOR mediates phosphoinositide 3-kinase and Akt/PKB signaling, resulting in phosphorylation of 4EBP1, and initiation of mRNA translation. A second pathway involves regulation of ribosomal S6 kinase, which affects ribosome biogenesis and translation elongation. Mutations affecting the gene results in Smith-Kingsmore syndrome.
