Product details:
Phospho-mTOR (S2448) and Total mTOR ELISA Kit (ab279869) is a very rapid, convenient, and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated mTOR protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.
This Sandwich ELISA kit is an
in vitro
enzyme-linked immunosorbent assay for the measurement of human phospho-mTOR and total mTOR. An anti-pan mTOR antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and mTOR present in a sample is bound to the wells by the immobilized antibody and the wells are washed. In select wells, rabbit anti-phospho mTOR (S2448) antibody is added to detect phosphorylated mTOR. In the remaining wells, biotinylated anti-pan-mTOR antibody is used to detect pan mTOR. After washing away unbound antibody, HRP-conjugated anti-rabbit IgG or HRP-conjugated Streptavidin is pipetted into the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of mTOR (S2448) or pan mTOR bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

The mammalian target of rapamycin commonly known as mTOR is a serine/threonine kinase known for its role in cellular growth and metabolism. It has a molecular weight of approximately 289 kDa. mTOR is expressed in various tissues throughout the body including muscle adipose tissue and the brain. The protein functions as a central regulator of cell proliferation protein synthesis and nutrient signaling. Often researchers utilize mTOR ELISA or mTOR western blot (mTOR WB) methods and mTOR antibodies to study its expression and activity in various biological contexts.
Biological function summary
MTOR integrates signals from nutrients growth factors and cellular energy status to maintain cellular homeostasis. It forms part of two distinct complexes mTORC1 and mTORC2 which differ in their component proteins and downstream effects. mTORC1 primarily responds to amino acids and regulates protein synthesis through phosphorylation of key substrates like S6K1. On the other hand mTORC2 is important for maintaining cytoskeletal integrity and cell survival highlighting the protein's importance in diverse cellular processes.
Pathways
MTOR plays a pivotal role in the PI3K/AKT/mTOR pathway which governs cell growth proliferation and survival. It also has implications in the regulation of the AMPK pathway which senses cellular energy levels. Through these pathways mTOR interacts with proteins such as AKT and TSC2. The phospho-mTOR specifically the S2448 phospho-mTOR serves as an important functional marker in these signaling cascades linking extracellular signals to downstream cellular responses.
MTOR has connections to cancer and neurodegenerative diseases. Its dysregulation often leads to uncontrolled cellular proliferation a hallmark of many cancers. Conditions such as tuberous sclerosis can occur due to mutations in proteins like TSC1 and TSC2 that regulate mTOR activity. In Alzheimer's disease mTOR's role in autophagy and protein synthesis becomes significant as imbalance may contribute to disease progression. Understanding these connections highlights the potential of targeting mTOR pathways therapeutically.
