qFlamma® Black01 NHS ester

qFlamma® Black01 NHS ester 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. NHS esters readily react with or amino groups of probes, peptides or the amine terminus of nucleotides to form a chemically stable amide bond between the quencher and the biomolecule. We offer qFlamma® Black01 NHS ester as a universal quencher in the construction of a variety of hybridization and custom-synthesized activatable probes for multiplexed bio-analysis, PCR, nucleic acid hybridization, etc.
