Typical Data
Positive Control
A431 cells were treated with recombinant human EGF at 37°C for 20 min. Cells were solubilzed at 4 x 107 cells/ml in Cell Lysate Buffer. Serial dilutions of lysates were analyzed in this ELISA (see Reagent Preparation step 4).
FBS Stimulation of 293 Cell Lines
293 cells were untreated or treated with 20% FBS for 20 min. Cell lysates were analyzed using this phosphoELISA. A431 cells were treated with recombinant human EGF at 37°C for 20 min. Cell lysates were analyzed using Western Blot.Â
Storage/Stability
Upon receipt, the kit should be stored at –20°C. Please use within 6 months from the date of shipment.
I used 150 µg of mouse liver lysate with overnight 4C incubation and the assay kit worked. Easy protocol to follow.

The Human and Mouse Phospho-mTOR (Ser2448) and Total mTOR ELISA was used to study the role of mTOR signaling in genotoxics-induced stress. We are very happy with this product.
