Revvity, 64BDSTGMPEG, HTRF Mouse STING (WT) Binding Kit, 500 Assay Points

Overview
A fast and easy way to identify new binders to mouse STING WT.
Stimulator of interferon genes (STING), also known as transmembrane protein 173 (TMEM173), is a protein playing a major role in innate immunity. Upon intracellular cytosolic DNA release from pathogens such as viruses and bacteria, 2’-3’cGAMP binds to STING protein and triggers the secretion of type 1 interferon. Identifying new STING ligands is therefore a way to control immunity and fight autoinflammatory diseases.
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
Assay principle
The HTRF STING binding assay is a competitive assay format which uses d2-labeled STING ligand, a 6His tagged mouse STING protein, and an anti 6His Cryptate-labeled antibody. Your compound competes with the STING ligand-d2 and thereby prevents FRET from occurring.

Assay protocol
The Mouse STING binding assay can be run in a 96- or 384-well low volume white plate (20 µL final). As described here, samples or standards are dispensed directly into the assay plate, the mouse His-tagged STING protein is then added followed by the dispensing of the HTRF reagents: the anti 6His antibody labeled with Terbium cryptate and  the STING ligand labeled with d2. The reagents labelled with HTRF fluorophores may be pre-mixed and added in a single dispensing step. No washing steps are needed. The protocol can be further miniaturized or upscaled by simply resizing each addition volume proportionally. Application-Protein-Protein Interaction
