Typical Data
Positive Control
HeLa cells were treated with Calyculin A. 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.
Calyculin A Stimulation of HeLa Cell Lines
HeLa cells were treated or untreated with Calyculin A. 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.
Although the signal of my samples (293T cell extracts) was low the standard provided created a nice curve giving me confidence in the data. I would really like to find a quantitative ELISA but a semi-quantitative is the next best thing for now.
