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.


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