Typical Data
Positive Control
HT29 cells were treated with Calyculin A. Solubilize cells at 4 x 10
7 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 HT29 Cell Line
HT29 cells were treated with Calyculin A. Cell lysates were treated or untreated with Lambda Protein Phosphatase (LPP) and analyzed using this phosphoELISA and Western Blot.


Storage/Stability
