KeyTec® TR-FRET mAb anti-GST-LA is designed for developing the TR-FRET Assay. The anti-GST antibody is a mouse monoclonal antibody. In the Protein-Protein Interaction assay, one GST-tagged protein binds to the acceptor (KeyTec® TR-FRET mAb anti-GST-LA*1), and the other protein is labeled (directly or indirectly) with the donor (KeyTec® TR-FRET Eu/Tb*2). When the two proteins 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 protein interaction.
KeyTec® TR-FRET mAb anti-GST-HX is designed for developing the TR-FRET Assay. The anti-GST antibody is a mouse monoclonal antibody. In the Protein-Protein Interaction assay, one GST-tagged protein binds to the acceptor (KeyTec® TR-FRET mAb anti-GST-HX*1), and the other protein is labeled (directly or indirectly) with the donor (KeyTec® TR-FRET Eu/Tb*2). When the two proteins 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 protein interaction.
