Revvity, 64ND3PEH, HTRF Human Total SMAD3 Detection Kit, 10,000 Assay Points

Overview
The total SMAD3 cellular assay kit is designed to monitor the expression level of SMAD3, whether phosphorylated or unphosphorylated. It is compatible with our Phospho-SMAD3 kit, and enables analysis of phosphorylated and total proteins from a single sample for better readout of TGF-ß signaling activity.
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-SMAD3 assay principle
The Total-SMAD3 assay quantifies the expression level of SMAD3 in a cell lysate. Contrary to Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis or transfer. The Total-SMAD3 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 SMAD3 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-SMAD3 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-SMAD3 HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

Total-SMAD3 1-plate assay protocol
Detection of total SMAD3 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
