Ask a question
Do you have a recommended protocol for immobilizing any avi-tagged recombinant proteins on a streptavidin coated plate? 02/01/2023

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.

What is the primary role of ERBB2 in cell signaling? 08/12/2022

ERBB2 is a receptor tyrosine kinase involved in the regulation of cell growth and differentiation.

What therapeutic agents target ERBB2 in cancer treatment? 10/03/2020

Therapeutic agents targeting ERBB2 include trastuzumab and lapatinib.

In which types of cancer is ERBB2 commonly overexpressed? 05/12/2020

ERBB2 is commonly overexpressed in breast, ovarian, and stomach cancers.

How does ERBB2 overexpression affect patient prognosis in cancer? 05/04/2019

ERBB2 overexpression is often associated with aggressive disease and poor prognosis.

How can ERBB2 levels be assessed in a clinical setting? 08/27/2018

ERBB2 levels can be assessed using immunohistochemistry and fluorescence in situ hybridization (FISH) in tissue samples.

How is ERBB2 involved in cell growth and proliferation? 08/07/2018

It forms heterodimers with other ERBB receptors, activating pathways that promote cell growth and survival.
