Human Fc gamma RI / CD64 binding Kit (TR-FRET) is based on a homogeneous (no wash) competition TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer) to measure the interaction between human CD64 and antibody drug candidates or CD64 inhibitors. It is designed to facilitate the ADCC and ADCP functional performance evaluation of antibody drug candidates, high-throughput screening of CD64 inhibitors within 0.5-1 hours. It can also be used as a universal detection tool to identify the ability of antibody drugs to bind to human CD64.

1. Unopened kit should be stored at 2℃-8℃ upon receiving.

2. Find the expiration date on the outside packaging and do not use reagents past their expiration date.

3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

This Human Fc gamma RI / CD64 binding kit (TR-FRET) is based on TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer). This assay uses the mixture of biotinylated human Fc gamma RI / CD64 and Europium-chelate labeled streptavidin as the Donor and FA labeled human IgG antibody as the Acceptor.

— When the sample does not contain human Fc gamma RI / CD64 binding components, the Donor and Acceptor are in close proximity because of the binding of human Fc gamma RI / CD64 and human IgG antibody. 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 human Fc gamma RI / CD64 binding components, the components inhibit the binding between the Donor and Acceptor and thereby prevent FRET from occurring.
