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/IL-1 beta Stimulation of HeLa Cell Line
HeLa cells were treated with Calyculin A and IL-1 beta. Cell lysates were treated or untreated with Lambda Protein Phosphatase (LPP) and 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.
