  • 产品概述(Product Overview)

    The Human Fc gamma RIIA / CD32a (R167) 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 CD32a (R167) and antibody drug candidates or CD32a (R167) inhibitors. It is designed to facilitate the ADCC and ADCP functional performance evaluation of antibody drug candidates, high-throughput screening of CD32a (R167) 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 CD32a (R167).

  • 存储(Storage)

    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.

  • 原理(Assay Principles)

    Human Fc gamma RIIA / CD32a (R167) binding kit (TR-FRET) is based on TR-FRET technology (Time-Resolved Fluorescence Resonance Energy Transfer). Use the mixture of biotinylated human Fc gamma RIIA / CD32a (R167) and Europium-chelate labeled streptavidin as the donor, FA labeled Human IgG1 antibody as the acceptor.

    - In the absence of human Fc gamma RIIA/CD32a (R167) binding components, the donor and acceptor are in close proximity due to the binding of human Fc gamma RIIA/CD32a (R167) and FA-labeled Human IgG1 antibody. 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 human Fc gamma RIIA/CD32a (R167) binding components, they disrupt the donor-acceptor interaction, preventing FRET from occurring.

     Fc gamma RIIA / CD32a TR-FRET

    Inhibition Assay of interaction of Europium-chelate labeled human Fc gamma RIIA / CD32a (R167) and FA labeled human lgG by Human IgG standard in a homogeneous (no wash) TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) competition assay, with a typical IC50 of 913 nM (QC tested).

  •  Fc gamma RIIA / CD32a TR-FRET

    The kit has been used to detect different subclasses of Human IgG (Human IgG1, Human IgG2, Human IgG3 and Human IgG4), which exhibit different IC50 results as expected. As shown in the following figure, human CD32a (R167) binds to human IgG1, IgG2, IgG3 and IgG4 with low affinity.

  •  Fc gamma RIIA / CD32a TR-FRET

    The kit has been used to detect different subclasses of mouse IgG (mouse IgG1, mouse IgG2a and mouse IgG2b), which exhibit different IC50 results as expected. As shown in the figure, human CD32a (R167) binds to mouse IgG1, mouse IgG2a, and mouse IgG2b with low affinity as observed, and mouse IgG1 show the higher affinity than mouse IgG2a or mouse IgG2b.

  •  Fc gamma RIIA / CD32a TR-FRET

    The kit has been used to detect four FDA approved antibody drugs with different affinities binding to human CD32a (R167). Bevacizumab, Toripalimab, Eculizumab and Efgartigimod alfa bind to human CD32a (R167) with the low affinity from 1 μM to 10 μM.

  •  Fc gamma RIIA / CD32a TR-FRET

    Verify potential matrix effects by adding different levels of DEME, RPMI1640, FBS and HSA to the Sample Diluted buffer.
