Recombinant Human HER2 (V777_G778insCG), GST-tagged

• Cat.No.: ERBB2-61H
• Product Overview: Recombinant human HER2 (V777_G778insCG) (676-end) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag.

Specification

• Species: Human
• Source: Sf9 Cells
• Tag: GST
• Protein Length: 676-end a.a.
• Description: HER2 gene encodes a cell-surface glycoprotein tyrosine kinase receptor with extensive homology to the epidermal growth factor receptor. HER2 is an oncogene and overexpression of unaltered HER2 coding sequences in NIH 3T3 cells results in cellular transformation and tumorigenesis. HER2 is amplified in about 30% of primary human breast malignancies and overexpression of HER2 is associated with the most aggressive tumors that show uncontrolled proliferation, resistance to apoptosis and increased motility.
• Form: 50mM Tris-HCl, pH 7.5, 150mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol.
• Molecular Mass: ~116 kDa
• Applications: Kinase Assay
• Storage: Store product at –70oC. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Q&As

Do you have a recommended protocol for immobilizing any avi-tagged recombinant proteins on a streptavidin coated plate?

1.Prepare the streptavidin-coated plate by washing it with PBS (phosphate-buffered saline) or another suitable buffer to remove any impurities. 2.Dilute the Avi-tagged protein in the desired buffer at the desired concentration. It is important to use a buffer that is compatible with the protein and does not interfere with its activity or stability. 3.Add the diluted protein to the streptavidin-coated plate and incubate it for a suitable amount of time at room temperature or 4°C. The exact conditions will depend on the specific protein and the desired level of immobilization. 4.Wash the plate with a suitable buffer to remove any unbound protein. 5.Block the remaining binding sites on the plate with a suitable blocking agent such as BSA (bovine serum albumin) or casein. 6.Wash the plate again to remove any unbound blocking agent. 7.Use the immobilized protein for further experiments such as ELISA, Western blotting, or other assays.
