Typical Data
Positive Control
HUVEC cells were treated with PV (Pervanadate). 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.

PV Stimulation of HUVEC Cell Line
HUVEC cells were treated or untreated with pervanadate. Cell lysates were analyzed using this phosphoELISA and Western Blot.


Storage/Stability
