WebCyanine dyes are normally added once at the 5’-terminus and the MMT group should be removed on the synthesizer. The absorbance of the MMT cation (yellow) is noticeably different from the DMT cation (orange), and so, absorbance-based trityl monitors will detect it incorrectly as a low coupling. Web• Absorbance at 280 nm (A 280) is used to determine the protein concentration in a sample. However, because fluorescent dyes also absorb at 280 nm, a correction factor must be used to adjust for amount of A 280contributed by the dye. The correction factor (CF) equals the A 280of the dye divided by the A maxof the dye.
