Revvity, 64BRD2TPEG, HTRF Human Total BRD2 Detection Kit, 500 Assay Points

Overview
BRD2 belongs to the bromodomain (BRD) Family II (BET). Like the other BRD family proteins, it binds to acetylated lysine and acts as a reader of the lysine acetylation state of proteins such as histones. It is a transcriptional regulator involved in many cell processes (embryogenesis, cycle regulation, development) through the E2F-RB pathway. BRD2 dysregulation is has been widely linked to many cancers, as it regulates the transcription of several oncogenes such as c-MYC ad Bcl-2.
Thus, inhibition of the BRD2 function has become part of the strategy for cancer treatments. More recently, targeting BET family protein degradation, including BRD2 via PROTAC molecules, has emerged as a novel and promising therapeutic approach.
How it works
Total-BRD2 assay principle
The HTRF Total-BRD2 assay quantifies the expression level of BRD2 in a cell lysate. Unlike Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis, or transfer. The Total-BRD2 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 BRD2 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 protein’s expression under a no-wash assay format

 

Total-BRD2 two-plate assay protocol
The two-plate protocol involves culturing cells in a 96-well plate before lysis, then transferring lysates into a 384-well low volume detection plate before the addition of Total-BRD2 HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

Total-BRD2 one-plate assay protocol
Detection of Total-BRD2 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
