|Recombinant Human HER3 / ErbB3 Protein (Catalog#10201-H08H)|
|0.2 μm filtered solution in PBS|
|This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human HER3 / ErbB3 (rh HER3 / ErbB3; Catalog#10201-H08H; NP_001973.2; Met 1-Thr 643). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.|
No cross-reactivity in ELISA with
Human ErbB2 / HER2
Human ErbB4 / HER4
Human EGFR / ErbB1 / HER1
Human cell lysate (293 cell line)
This antibody can be used at 1:1000-1:2000 with the appropriate secondary reagents to detect Human ErbB3.
Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
Application: ELISA WB IP
ErbB3, also known as Her3(human epidermal growth factor receptor3), is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound glycoprotein has a neuregulin binding domain but has not an active kinase domain., and therefore can not mediate the intracellular signal transduction through protein phosphorylation. However, its heterodimer with ErbB2 or other EGFR members responsible for tyrosine phosphorylation forms a receptor complex with high affinity, and initiates the related pathway which lead to cell proliferation or differentiation. ErbB3 has been shown to implicated in numerous cancers, including prostate, bladder, and breast tumors. This protein has different isoforms derived from alternative splicing variants, and among which, the secreted isoform lacking the intermembrane region modulates the activity of membrane-bound form.
