Ab38503, at a 1/50 dilution, staining EGFR in paraffin embedded human breast carcinoma tissue by Immunohistochemistry.
Left image: untreated.
Right image: treated with synthesized phosphopeptide
All lanes : Anti-EGFR (phospho S1070) antibody (ab38503) at 1/500 dilution
Lane 1 : SK-OV3 cell extract
Lane 2 : SK-OV3 cell extract treated with EGF
Lysates/proteins at 30 µg per lane.
Secondary
Alkaline Phosphatase AffiniPure Goat Anti-Rabbit IgG (H+L)
Predicted band size : 134 kDa
Observed band size : 160 kDa (why is the actual band size different from the predicted?)
The amount of cell extract loaded for the WB was 5-30 ug of total protein.
The 160 kDa protein band shown in the Western blot image is the glycosylated form of EGFR.
