Other Notes
Small volumes of anti-ERBB3 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Applications Tested/Suitable for anti-ERBB3 antibody
Peptide ELISA (EIA), Western Blot (WB)
Application Notes for anti-ERBB3 antibody
Peptide ELISA: Antibody detection limit dilution 1: 32000.
Western Blot: Approx 150kDa band observed in human lysates of T cell line JURKAT (calculated MW of 148kDa according to NP_001973.2). Recommended concentration: 0.1-0.3ug/ml. A minor band of unknown identity was also consistently observed at 48kDa. This band was successfully blocked by incubation with the immunising peptide.

Western Blot (WB) of anti-ERBB3 antibody
(0.1ug/ml) staining of Jurkat lysate (35ug protein in RIPA buffer) with (B) and without (A) blocking with the immunising peptide. Primary incubation was 1 hour. Detected by chemiluminescence.

NCBI Summary for ERBB3
This gene encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized. [provided by RefSeq, Jul 2008]
UniProt Comments for ERBB3
HER3: a receptor tyrosine kinase of the EGFR family. Binds and is activated by neuregulins and NTAK. Can form homodimers or ErbB-2/ErbB-3 heterodimers. Kinase domain lacks activity but heterodimerizes with other EGFRs to transduce growth signals. May be required for HER2 activity. Elevated expression in breast and other tumors is indicative of poor outcome. A secreted form is expressed in metastatic prostate cancer Two alternatively spliced isoforms have been described.
