Revvity, 64NRSPEH, HTRF Human and Mouse Total IRS1 Detection Kit, 10,000 Assay Points

Overview
The HTRF total IRS1 assay is designed to be used as a normalization assay with our Phospho-IRS1 kits. Total IRS1 assay is optimal to monitor insulin resistance. IRS1 is a relevant marker for insulin resistance, tumor development, and metastatic progression. It is associated with type 2 diabetes, obesity, and cancer.
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-IRS1 assay principle
The total IRS1 assay quantifies the expression level of IRS1 in a cell lysate. Contrary to Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis or transfer. The total IRS1 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 IRS1 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-IRS1 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 IRS1 HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

Total-IRS1 1-plate assay protocol
Detection of total IRS1 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
