A. Laurent et al., CONVENIENT METHOD FOR LABELING OLIGONUCLEOTIDE ANALOGS BY A FLUOROGENIC TAG FOR DIRECT IN-VITRO AND IN-VIVO VISUALIZATION OF CARBOXYESTERASE ACTIVITY, Nucleosides & nucleotides, 16(7-9), 1997, pp. 1765-1766
The synthesis of two oligonucleoside phosphorothioate and methylphosph
onate analogs functionalized with a fluorogenic tag is described. The
fluorescent conjugate formation is demonstrated in cell culture medium
, cell extracts and in human fibroblasts.
