Revvity, 64NH3PEG, HTRF Human and Mouse Total Histone H3 Detection Kit, 500 Assay Points

Overview
The Total Histone H3 cellular assay kit is used as a normalization assay with phospho-Histone H3 kits. Histone H3 is a key regulator of gene expression and mitosis, making it a powerful tool for anti-cancer research.
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-Histone H3 assay principle
The Total-Histone H3 assay quantifies the expression level of Histone H3 in a cell lysate. Contrary to Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis or transfer. The Total-Histone H3 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 Histone H3 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-Histone H3 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 Histone H3 HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

Total-Histone H3 1-plate assay protocol
Detection of total Histone H3 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
