Weblikely to contribute to a better understanding of the mechanisms of photobleaching given the central importance of dye triplet states in photobleaching processes. The approach was applied to the measurement and characterization of the photobleaching of Rh6G in aqueous solution and FITC in 1 mM sodium carbonate buffer (pH 9). The WebFITC is a particular form of reactive species, the isothiocyanate, of the dye. It yields a urea linkage upon reaction with a primary amine. 6-FAM is the preferred reagent for labeling an oligonucleotide. It results in an amide bond when reacted with a primary amine. The chemistry is more robust and better yielding. literary forms of the bible
