The KeyTec® TR-FRET Human IgG detection kit is designed for quantitative measurement of human IgG in supernatant. It is based on sandwich immunoassay model and utilizes TR-FRET technology, known for its ease of use, homogeneity (no wash), low background, high sensitivity, robustness.
The screening principle is based on TR-FRET technology. The mAb anti-hFc antibody is labeled with KeyTec® TR-FRET Solar Eu and pAb anti-hFab antibody is labeled with KeyTec® TR-FRET LA, when mAb anti-hFc-Solar Eu and pAb anti-hFab-LA bind to Human IgG, the donor molecule is brought into proximity with the acceptor molecule. Excitation of the donor will result in the generation of the TR-FRET signal at 665 nm, proportional to the concentration of Human IgG.
