Recombinant Human ERBB2

• Cat.No.: ERBB2-26845TH
• Product Overview: Recombinant fragment, corresponding to 1 initial methionine + amino acids 23 - 340 of Human ErbB 2 + 79 amino acids of intron 8.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 23-340 a.a.
• Description: This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized.
• Tissue specificity: Expressed in a variety of tumor tissues including primary breast tumors and tumors from small bowel, esophagus, kidney and mouth.

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.
