  • 产品概述(Product Overview)

    The Human TL1A-DR3 inhibition 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 TL1A binding to human DR3 within 0.5-1 hours. It can also be used as a universal detection tool to identify the ability of TL1A to bind to human DR3.

  • 原理(Assay Principles)

    This Human TL1A-DR3 inhibition kit (TR-FRET) is based on TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer). Use a mixture of biotinylated human TL1A and Europium-chelate labeled streptavidin as the donor and FA labeled human DR3 protein as the acceptor.

    - In the absence of inhibitors for human TL1A binding to human DR3, the donor and acceptor are in close proximity due to the binding of human TL1A and FA-labeled human DR3. 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 TL1A to human DR3, the donor-acceptor interaction is disrupted, preventing FRET from occurring.

     TL1A-DR3 TR-FRET

    Inhibition of Europium-chelate labeled human TL1A: FA labeled human DR3 binding by Human Anti-TL1A Neutralizing Antibody
    Premix serial dilutions of Human Anti-TL1A Neutralizing Antibody (1:2 serial dilution, from 10 μg/mL to 0.01953125 μg/mL (66.6667-0.1302 nM)) and Human TL1A Protein Europium-chelate and incubate at room temperature (20℃-25℃) for 0.5 hours. Then add FA Labeled Human DR3 Protein and incubate at room temperature (20℃-25℃) for 0.5 hours. Detection was performed with IC50 of 2.816nM. The assay was performed according to the above-described Datasheet (QC tested).

背景介绍

The TL1A protein, belongs to the tumor necrosis factor (TNF) family and is a receptor for TNFRSF25 and TNFRSF6B. TL1A is involved in the activation of NF-κB and C-Jun pathways, which can be used as a regulator of mucosal immunity and participate in the immune pathway of inflammatory bowel disease (IBD) pathogenesis.
