The Human IL-5 / IL-5Rα Inhibitor Screening Kit (TR-FRET) is based on a homogeneous (no wash) competition TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer) to screening for inhibitors of human IL-5 binding to human IL-5Rα within 0.5-1 hours. It can also be used as a universal detection tool to identify the ability of human IL-5 to bind to human IL-5Rα.

This Human IL-5 / IL-5Rα Inhibitor Screening Kit (TR-FRET) is based on TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer). Use a mixture of biotinylated human IL-5 R alpha and Europium-chelate labeled streptavidin as the donor and FA labeled human IL-5 as the acceptor.
— In the absence of inhibitors for human IL-5 R alpha binding to human IL-5, the donor and acceptor are in close proximity due to the binding of human IL-5 R alpha and human IL-5. Upon excitation with a specific light source, the donor emits a 620 nm signal, which is absorbed by the acceptor, resulting in a 665 nm emission.
— In the presence of inhibitors that block the binding of human IL-5 R alpha to human IL-5, the donor-acceptor interaction is disrupted, preventing FRET from occurring.

Inhibition of Europium-chelate labeled Human IL-5 R alpha Protein:FA Labeled Human IL-5 binding by Monoclonal Anti-IL-5 R alpha Antibody
Premix serial dilutions of Monoclonal Anti-IL-5 R alpha Antibody (1:2 serial dilution, from 20 μg/mL to 0.02 μg/mL (133.33-0.13 nM)) and Human IL-5 R alpha Protein Europium-chelate. Then add FA Labeled Human IL-5 and incubate at room temperature (20℃-25℃) for 1 hours. Detection was performed with IC50 of 4.323 nM. The assay was performed according to the above-described Datasheet (QC tested).
The kit is suitable for the detection of IL-5 / IL-5Rα inhibitors. It shows that both Benralizumab and Mepolizumab exhibit good inhibitory activity in this TR-FRET competition assay.
