Typical Data
Positive Control
HUVEC cells were treated with Pervanadate (PV). Cells were solubilzed at 4 x 10
7 cells/ml in Cell Lysate Buffer. Serial dilutions of lysates were analyzed in this ELISA (see Reagent Preparation step 4).

PV Stimulation of HUVEC Cell Line
HUVEC cells were untreated or treated with PV. 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.
