Background Information
ERBB1, also named as EGFR, is a receptor for EGF, but also for other members of the EGF family, as TGF-alpha, amphiregulin, betacellulin, heparin-binding EGF-like growth factor, GP30 and vaccinia virus growth factor. ERBB1 is involved in the control of cell growth and differentiation. Phosphorylates MUC1 in breast cancer cells and increases the interaction of MUC1 with C-SRC and CTNNB1/beta-catenin. Isoform 2/truncated isoform of ERBB1 may act as an antagonist. EGFR is associated with lung cancer. The antibody is specific to isoform1.

Reviews
What customers say
Users report this antibody performs well across WB, IF, and IHC on human, mouse, and rat samples. Typical dilutions are 1:500–1:1000 for WB and 1:200 for IF/IHC. One reviewer noted a strong band near 170 kDa with a fainter one below 130 kDa. Another confirmed it works on PFA-fixed tissue without antigen retrieval. Minor concerns include some non-specific lower-molecular-weight bands in WB and difficulty detecting the phosphorylated form. Overall, the antibody is considered reliable with an average rating of 4.4/5.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Marina (Verified Customer) (02-13-2023) | A stronger band can be observed slighly above 170 kDa and a fainter band below 130 kDa. Ponceau red is used as total protein loading control. Primary antibody dilution 1:500, overnight incubation at 4ºC. Exposure time 3 minutes.
|
Clarisse (Verified Customer) (12-12-2022) | This antibody works very well on tissue fixed overnight at 4 degrees C with 2% PFA. No antigen retrieval required.
|
Morgan (Verified Customer) (10-26-2021) | I had luck with this antibody as seen from the image attached. It took a little bit of time to develop though. Maybe using more than 1:500 would be better. Unfortunately I couldn't get the phosphorylated version (p-EGF) to work though. I used OV90 (ovarian cancer) cells

K (Verified Customer) (12-20-2020) | worked well for WB (1:1000)IF (1:200)and IHC (1:200)

XB (Verified Customer) (10-29-2020) | It is OK to use it to probe EGFR (about 180 kD), but there are some unspecific bands at the lower part of the gel.
