Revvity, 64NR2PEH, HTRF Human Total ErbB2 (HER2) Detection Kit, 10,000 Assay Points

Overview
The Total HER2 cellular assay kit monitors HER2 and is used as a normalization assay with the phospho-HER2 kit. Upregulation of HER2, or human epidermoid receptor 2, also known as ErbB2 receptor, is associated with human breast cancer and several others, such as ovarian, stomach, bladder, salivary, or lung carcinomas, making HER2 a key target for anti-cancer therapies.
HTRF assays offer many advantages over other technologies:

Homogeneous add-and-read format
No wash steps
Low background
Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates
Stable signal, providing flexibility in time of readout or size of assays
How it works
Total-HER2 assay principle
The Total-HER2 assay quantifies the expression level of HER2 in a cell lysate. Contrary to Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis or transfer. The Total-HER2 assay uses two labeled antibodies: one coupled to a donor fluorophore, the other to an acceptor. Both antibodies are highly specific for a distinct epitope on the protein. In presence of HER2 in a cell extract, the addition of these conjugates brings the donor fluorophore into close proximity with the acceptor and thereby generates a FRET signal. Its intensity is directly proportional to the concentration of the protein present in the sample, and provides a means of assessing the proteins expression under a no-wash assay format.

 

Total-HER2 2-plate assay protocol
The 2 plate protocol involves culturing cells in a 96-well plate before lysis then transferring lysates to a 384-well low volume detection plate before adding Total HER2 HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

Total-HER2 1-plate assay protocol
Detection of total HER2 with HTRF reagents can be performed in a single plate used for culturing, stimulation and lysis. No washing steps are required. This HTS designed protocol enables miniaturization while maintaining robust HTRF quality. Application-Cell Signaling
