Immunohistochemical analysis of paraffin-embedded human Esophageal Carcinoma tissue using Phospho-mTOR antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P80837, 1:200 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium.

Tyramide signaling amplification based immunofluorescence was performed on paraffin-embedded human Cervical Cancer tissue using Phospho-mTOR (Ser2448) antibody. Antigen retrieval was performed in EDTA buffer pH 9.0 (95 °C, 20 min) followed by cooling to RT. Then incubated with primary antibody (HY-P80837, 1:500 dilution) at room temperature for 60 minutes and HRP conjugated secondary antibody for 10 minutes. Fluorescence was then developed with Vari Fluor 532 TSA (200×)(HY-D1832). The tissues were counterstained with DAPI and mounted with Anti-fade mounting medium.

Background

Function
mTOR (mammalian target of Rapamycin) is a protein that in humans is encoded by the mTOR gene. mTOR is a serine/threonine protein kinase that regulates cell growth, cell proliferation, cell motility, cell survival, protein synthesis, and transcription. mTOR belongs to the phosphatidylinositol 3-kinase-related kinase protein family. mTOR integrates the input from upstream pathways, including growth factors and amino acids. mTOR also senses cellular nutrient, oxygen, and energy levels. The mTOR pathway is dysregulated in human diseases, such as diabetes, obesity, depression, and certain cancers. Rapamycin inhibits mTOR by associating with its intracellular receptor FKBP12. The FKBP12-rapamycin complex binds directly to the FKBP12-Rapamycin Binding (FRB) domain of mTOR, inhibiting its activity.
