Fluorescein Biotin

Description: Fluorescein Biotin is a biotin-substituting fluorescent dye that detects and quantifies biotin binding sites by fluorescence or absorbance.Fluorescein Biotin undergoes fluorescence quenching when bound to avidin or streptavidin. Target: Autophagy. Smiles: O=C1OC2(C=3C1=CC(NC(NCCCCCNC(CCCCCNC(CCCC[C@H]4[C@@]5([C@](CS4)(NC(=O)N5)[H])[H])=O)=O)=S)=CC3)C=6C(OC=7C2=CC=C(O)C7)=CC(O)=CC6. References: Gruber HJ, et al.
