• Cat.No.: ERBB2-81H
• Product Overview: Recombinant Human Her-2/neu(erbB-2)-Fc, was expressed in NSO cells, amino acids 630((23-652aa), IgG-Fc (100-330aa) his-tag fusion protein

Specification

• Species: Human
• Source: Mammalian Cells
• Tag: Fc&His
• Protein Length: 23-652 a.a.
• Description: HER2/neu (also known as ErbB-2, ERBB2) is a protein highly expressed in breast cancers.The herstatin mRNA is expressed in normal human fetal kidney and liver, but is at reduced levels relative to p185HER-2 mRNA in carcinoma cells that contain an amplified HER-2 gene. Herstatin appears to be an inhibitor of p185HER-2, because it disrupts dimers, reduces tyrosine phosphorylation of p185, and inhibits the anchorage-independent growth of transformed cells that overexpress HER-2.
• Molecular Mass: ~130 kda under reducing conditions
• Purity: >95%
• Usage: This item is for LABORATORY RESEARCH USE ONLY.

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.
