BODIPY FL VH032 is a high-affinity VHL fluorescent probe (Kd= 3.01 nM) with application in time-resolved fluorescence resonance energy-transfer (TR-FRET) assays for high-throughput identification and characterization of VHL ligands. BODIPY FL VH032 consists of a derivative of von Hippel-Lindau (VHL) ligand VH 032 and a fluorophore BODIPY FL(with excitation peak at 504 nm and emission peak at 520 nm), joined by a polyethylene glycol (PEG) 4 linker. The BODIPY FL VH032 VHL TR-FRET signal is stable through the 90 - 300 min incubation time, and theTR-FRET binding assay is sensitive, selective and resistant to assay interference. BODIPY FL VH032 also exhibits high VHL affinity in a fluorescence polarization (FP) assay. Excitation maximum ~ 504 nm; emission maximum ~ 520 nm.
NFQ1 作为一种非荧光淬灭剂(吸收波长:474 nm),广泛应用于新型 One Sample Fluorescence Resonance Energy Transfer (OS-FRET) 方法中。该方法通过测量同一样品中未被淬灭的供体发射,利用 NFQ1 的宽广吸收光谱,确保其作为多种供体的有效暗接受剂。
