|Recombinant Human ErbB2 protein (Catalog#10004-H08H)|
|0.1M Sodium phosphate, 0.15M NaCl, pH 7.2, 3% BSA|
|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 ErbB2 / HER2 extracellular domain (rhErbB2; Catalog#10004-H08H; NP_004439.2; Met 1-Thr 652). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography and then biotinylated.|
|Human ErbB2 / HER2 / CD340|
No cross-reactivity in ELISA with Human ErbB1 / EGFR, Human ErbB3 / HER3, Human ErbB4 / HER4and Human cell lysate (293 cell line)
ELISA: 0.5-1 μg/mL
This antibody can be used at 0.5-1 μg/mL as a detection antibody to detect Human ErbB2 in ELISA.
|This antibody can be stored at 2℃-8℃ for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20℃ to -80℃. Preservative-Free.|
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.
Human epidermal growth factor receptor 2 (HER2), also known as ErbB2, NEU, and CD340, is a type I membrane glycoprotein, and belongs to the epidermal growth factor (EGF) receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.
