Typical Data

Positive Control
T47D cells were exposed to 50J/m2 of UV light followed by a 4 hours recovery period. 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).
UV irradiation of T47D Cell Line
T47D cells were untreated or treated with UV. Cell lysates were analyzed using this phosphoELISA and Western Blot. 


Upon receipt, the kit should be stored at –20°C. Please use within 6 months from the date of shipment.
