Fig. 8. TLR2/1 dimerization determined by TR-FRET in monocytes.
TR-FRET assay was used to detect dimerization of TLR2 with TLR1 using anti-TLR2. Antibodies labeled with europium cryptate as the donor fluorophore and anti-TLR1. Antibodies labeled with d2 as the acceptor fluorophore: an assay to detect the dimerization of native receptors in the context of intact cell membrane, whereas, X-ray crystallography or immunoprecipitation assays to detect dimerization uses truncated or epitope tagged recombinant receptor protein, respectively. (Snodgrass et al., 2013).
