Introduction
RayBio® Phospho-P53 (S15) ELISA kit is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in human, mouse and rat cell lysates. By determining phosphorylated P53 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, mouse and rat phospho-P53. An anti-P53 (S15) antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and phosphorylated P53 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-P53 antibody is used to detect phosphorylated P53. After washing away unbound antibody, HRP-conjugated streptavidin is pipetted to 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 P53 (S15). The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Typical Data
Positive Control
T47D cells were exposed to 50J/m2 of UV light followed by a 4 hours recovery period. Solubilize cells at 4 x 107 cells/ml in Cell Lysate Buffer. Serial dilutions of lysates were analyzed in this ELISA. Please see step 3 of Part VI Reagent Preparation for detail.
UV irradiation of T47D Cell Line
T47D cells were untreated or exposed to 50J/m2 of UV light followed by a 4 hours recovery period before lysis. Cell lysates were analyzed using this phosphoELISA and Western Blot.
Storage/Stability
Upon receipt, the kit should be stored at €“20°C. Please use within 6 months from the date of shipment. After initial use, Wash Buffer Concentrate (Item B), Assay Diluent (Item E), TMB One-Step Substrate Reagent (Item H), Stop Solution (Item I) and Cell Lysate Buffer (Item J) should be stored at 4°C to avoid repeated freeze-thaw cycles. Return unused wells to the pouch containing desiccant pack, reseal along entire edge, and store at €“20°C. Item D, store at 2-8°C for up to one month (store at -20°C for up to 6 months, avoid repeated freeze-thaw cycles). Reconstituted Positive Control (Item K) should be stored at -70°C.
