Rabbit anti Human ErbB3 antibody recognizes ErbB3 also known as receptor tyrosine-protein kinase erbB-3, proto-oncogene-like protein c-ErbB-3 and tyrosine kinase-type cell surface receptor HER3.

ErbB3 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 ErbB3 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).

Rabbit anti Human ErbB3 antibody detects a band of 185 kDa. The antibody has been extensively validated for western blotting using whole cell lysates.

Positive Control Lysate

Lysate Composition
400μg HepG2 lysate lyophilized in RIPA buffer.
Lysate Reconstitution
- If using DDT reconstitute the lyophilized lysate with 190μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 10μl 2M DTT.
- If using BME reconstitute the lyophilized lysate with 180μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 20μl BME.
Heat at 95°C for 5 minutes. For 10 well mini gels load 25μl. For other gel and comb formats please refer to the PrecisionAb western blotting protocol.
