BHQ-1 CPG *1000 Å*
BHQ-1 CPG is used to add the non-fluorescent quencher BHQ-1 to the 3' end of an oligonucleotide. BHQ-1 quencher has maximal absorption in the 480 to 580 nm range, which provides excellent quenching of fluorophores emitting in this range, eg Fluorescein, TET, JOE, HEX, etc. BHQ-1 Glycolate CPG has a glycolate linkage to the CPG support. The glycolate linker allows for rapid cleavage of the oligonucleotides and is labile enough for base sensitive oligonucleotides. The 1000 Å CPG is best suited for the synthesis of DNA sequences up to 100-mers in length.
