Product Specifications

Product Overview

The Human CD40 / CD40 Ligand Inhibitor Screening Kit (TR-FRET) is based on a homogeneous (no wash) competitive TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer) to screen for inhibitors of human CD40 binding to CD40 Ligand within 0.5-1 hours. It can also be used as a universal detection tool to identify the ability of human CD40 to bind to human CD40 Ligand.

Assay Principles

This Human CD40 / CD40 Ligand Inhibitor Screening Kit (TR-FRET) is based on TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer). This assay uses the mixture of biotinylated human CD40 Ligand and Europium-chelate labeled streptavidin as the Donor and FA Labeled Human CD40 Protein as the Acceptor.

— When the sample does not contain the inhibitors that block the binding of human CD40 Ligand to human CD40, the Donor and Acceptor are in close proximity because of the binding of human CD40 Ligand and human CD40. Upon Donor excitation with light of a specific wavelength (337nm), in addition to Donor emission (620nm), non-radiative transfer of energy occurs between Donor and Acceptor, resulting in Acceptor emission (665nm).

— When the sample contains the inhibitors that block the binding of human CD40 Ligand to human CD40, the components inhibit the binding between the Donor and Acceptor and thereby prevent FRET from occurring.
