VIC is an asymmetrical xanthene dye (two flanking rings are not the same). This dye is used for the design of qPCR probes. The spectral properties of VIC are similar to HEX and JOE.
This phosphoramidite reagent allows to introduce the label onto 5'-terminus of the oligonucleotide.
Recommendations for using the reagent:
Coupling: 10 minutes.
Deprotection: standard conditions with ammonium hydroxide; AMA (solution of 30% ammonium hydroxide/40% aqueous methylamine 1:1 v/v) (15 minutes at 65°C) can be used with minor side product forming.
