qFlamma® Black01 Vinylsulfone

qFlamma® Black01 Vinylsulfone is an amine  reactive form of universal dark quencher that the range of absorption covers from 400 to 800 nm with no native fluorescence. Black01 quencher displays high absorption coefficient, superb stability and aqueous solubility. Vinylsulfone reactive group, developed by BioActs’ leading technology, is stable in a wide range of pH and at the high temperature and reacts with primary amines of probes, proteins, peptides or amino-modified nucleotides to form a stable amino linkage between quencher and the biomolecule.We offer qFlamma® Black01 vinylsulfone as a universal dark quencher in the construction of a variety of hybridization and custom-synthesized activatable probes for multiplexed bio-analysis, PCR, nucleic acid hybridization, etc.
