Typical Data
Positive Control
A431 cells were treated with recombinant human EGF at 37°C for 20 min. Cells were solubilzed at 4 x 10
7 cells/ml in lysis buffer. Serial dilutions of lysates were analyzed in this ELISA. Please see step 3 of Part VI. Reagent Preparation for details.

Recombinant Human EGF Stimulation of A431 Cell Lines
A431 cells were treated or untreated with EGF. Cell lysates were analyzed using this phosphoELISA and Western Blot.


Storage/Stability
