Additional data
Additional Notes
This experiment was to test the cross reactivity with p-ErbB2.
The conclusion is that ab109273 strongly cross-reacts with p-ErbB2. There are two potential cross-reaction sites in ErbB2 (p-Y1196, p-Y1248).
ErbB2-EGFP was also detected by additional ErbB2 antibodies to confirm the expression and size (not included in the figure).
There is also possibility that ab109273 cross-reacts with p-EGFR (Y1138).
