3'-QSY21 CPG

Product Introduction

3'-QSY21 CPG is a non-fluorescent quencher designed for oligonucleotide synthesis, featuring a chromophore that efficiently absorbs and dissipates energy from adjacent fluorophores through non-radiative decay. It is incorporated into oligonucleotides to modulate fluorescence signals in molecular beacon assays and FRET-based applications, enhancing the dynamic range of fluorescence detection. The compound's conjugation to the 3' end of oligonucleotides enables precise control over probe design in nucleic acid hybridization studies, supporting advanced bioimaging and biosensing workflows.
