Protein-protein interaction is fundamental to signal transduction both within and between cells, as well as to metabolic regulation and biological reactions. Consequently, in-depth studies of these interactions not only enhance our understanding of intracellular biological mechanisms but also hold significant importance for drug research and development, as well as disease treatment. The KeyTec® TR-FRET Toolbox series offers a straightforward and rapid means of detecting protein-protein interactions, making it an excellent choice for drug screening and research into drug action mechanisms.

KeyTec® TR-FRET pAb anti-Human IgG-Solar Eu (100X)
KeyTec® TR-FRET pAb anti-Human IgG-Solar Eu (100X)
KeyTec® TR-FRET pAb anti-Human IgG-Solar Eu is designed for developing the TR-FRET Assay. The anti-Human IgG antibody is a mouse polyclonal antibody. In the Antigen-Antibody Interaction assay, the Human IgG antibody binds to the donor (KeyTec® TR-FRET pAb anti-Human IgG-Solar Eu*1), and the antigen is labeled (directly or indirectly) with the acceptor (KeyTec® TR-FRET LA/HX*2). When the Antigen-Antibody interact, 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 extent of antigen-antibody interaction.
