The Anti-mTOR (Phospho-Ser2448) antibody is a rabbit polyclonal antibody. It was tested on Western Blots for specificity. A single protein band was detected. This protein band can be blocked by the synthesized immunogen peptide.
The Anti-mTOR (Phospho-Ser2448) antibody is highly specific for the phospho-peptide in comparison to the non-phospho peptide counterpart, through an ELISA.
The Anti-mTOR antibody is a rabbit polyclonal antibody. It was tested on Western Blots for specificity. A single protein band was detected. This protein band can be blocked by the synthesized immunogen peptide.
The Anti-GAPDH antibody is a mouse monoclonal antibody. It was tested on Western Blots with the tissue lysates from human, mouse, and rat for specificity. A single protein band was detected from all three lysates.
1) Cell Line: The cell line must express the target protein. This protocol can be used directly for adherent cells. For suspension cells and loosely attached cells, two steps are required: Coat the plates with 100 µL of 10 µg/mL Poly-L-Lysine to each well of the 96-well plate for 30 minutes at 37°C before proceeding to Step 1 of Assay Protocol. Use 8% formaldehyde to fix the cells on Step 5 of Assay Protocol.
2) Cell Number and Sensitivity: The number of cells plated onto the 96-well plates depends on the expression level of mTOR protein in the cells, cell size, treatment conditions and incubation time. The cells used for testing should be around 75-90% confluent. Typically for HeLa cells, seed 30,000 cells per well overnight for treatment the following day. The mTOR (Phospho-Ser2448) Colorimetric Cell- Based ELISA Kit can detect Phospho-mTOR expression in as little as 5,000 HeLa cells.
3) Cell Treatment: The cells can be treated with inhibitors, activators, stimulators (ie. chemicals, proteins/peptides) or a combination of the substances listed above. The cells can be treated with UV and serum starvation to meet the needs of the end-user.
4) Positive and Negative Controls: Mouse Anti-GAPDH antibody (included) should be used to detect the internal positive controls for normalization of OD values of the target protein. The negative controls are HRP-Conjugated Anti-Rabbit IgG antibody and HRP- Conjugated Anti-Mouse IgG antibody alone in different wells (without the primary antibodies). Both positive and negative controls should be performed in the same plate with the Phospho-mTOR target experiments.
5) Accuracy and Precision: Each condition should be performed in duplicate or in triplicate.

Phospho-mTOR : Human:pSer-2448, Mouse:pSer-2448, Rat:pSer-2448
The Colorimetric Cell-Based ELISA Kit allows for the detection of various target proteins and the effects that certain stimulation conditions have on target protein expression in different cell lines. Qualitative determination of target protein concentration is achieved by an indirect ELISA format. In essence, the target protein is captured by target-specific primary (1st) antibodies while the HRP-conjugated secondary (2nd) antibodies bind the Fc region of the 1st antibody. Through this binding, the HRP enzyme conjugated to the 2nd antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are described:
1) a monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values.
2) Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method is used to determine cell density. After staining, the results can be analyzed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted.
3) If a phosphorylated target is being detected, an antibody against the non- phosphorylated counterpart will be provided for normalization purposes. The absorbance values obtained for the non-phosphorylated target can be used to normalize the absorbance values for the phosphorylated target.
mTOR (Phospho-Ser2448) Colorimetric Cell-Based ELISA
The mTOR (Phospho-Ser2448) Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can monitor mTOR protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated mTOR in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on mTOR phosphorylation.

4) Remove the cell culture medium and rinse with 200 µL of 1x TBS, twice.
5) Fix the cells by incubating with 100 µL of Fixing Solution for 20 minutes at room temperature. The 4% formaldehyde is used for adherent cells and 8% formaldehyde is used for suspension cells and loosely attached cells. During the incubation, the plates should be sealed with Parafilm. Note: Fixing Solution is volatile. Wear appropriate personal protection equipment (mask, gloves and glasses) when using this chemical.
6) Remove the Fixing Solution and wash the plate 3 times with 200 µL 1x Wash Buffer for five minutes each time with gentle shaking on the orbital shaker. The plate can be stored at 4°C for a week. Note: For all wash steps, tap the plate gently on absorbent papers to remove the solution completely.

|Calculation of Results||
Anti-mTOR antibody normalization: The OD values obtained for the phosphorylated target protein can be normalized using the OD values obtained for the non-phosphorylated target protein via the proportion, OD450 (Anti-mTOR P-Ser2448 antibody)/OD450 (Anti-mTOR antibody).
GAPDH normalization: The OD450 values obtained for the target protein (phosphorylated and non- phosphorylated) can be normalized using the OD450 values obtained for GAPDH.
Crystal Violet Staining normalization: The measured OD450 readings can be normalized using the OD595 values via the proportion, OD450/OD595.
