Immunofluorescence analysis of HER-3 was done on 70% confluent log phase MCF-7 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with HER-3 (2B5) Mouse Monoclonal Antibody (MA513040) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300).Panel d is a merged image showing cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

MA5-13040 targets HER-3 in IP and WB applications and shows reactivity with Human, mouse, and Rat samples.
The MA5-13040 immunogen is recombinant rat c-erbB-3/HER-3 oncoprotein.
c-erbB-3/HER-3 is the third member of the type I family of growth factor receptors. It binds to ligands in the heregulin family. c-erbB-3 is over-expressed in a variety of tumors including breast, stomach, pancreas, and colon. Heregulin & EGF stimulate tyrosine phosphorylation of c-erbB-3 to different extents.
IP-MS enrichment of ERBB3 (LFQ intensity): ERBB3 was enriched 231-fold from MCF7 lysate compared to background proteins, using the optimized IP-MS workflow with Pierce MS-Compatible Magnetic IP Kit protein A/G (Part No. 90409) and ERBB3 antibody (Part No. MA5-13040). The STRING database (www.string-db.org) was used to identify the protein interactor list. See more information on IP-MS verification of antibody selectivity. IP-MS validation info.

Oligomerization of the Nrdp1 E3 ubiquitin ligase is necessary for efficient autoubiquitination but not ErbB3 ubiquitination.
MA5-13040 was used in immunoprecipitation and western blot to study the requirement of Nrdp1 E3 ubiquitin ligase oligomer formation for self-ubiquitinylation by not for the unbiquitinylation of erbB3
