Sv. Kochetkova et al., Intercalating insert into internucleotide linkages as way for stabilization and detection of of short DNA duplexes, NUCLEOS NUC, 18(6-7), 1999, pp. 1495-1496
Simple and convenient method for stabilization and detection of duplexes of
short oligonucleotides with DNA was developed. This method is based on use
of oligonucleotides containing inercalating insert in internucleotide link
age. The linker is so long that dye can intercalate only into the same stac
king contact. Additionally the method allows to introduce into oligonucleot
ide as one intercalator as well as several identical or different intercala
ting dye.
