Xh. Cheng et al., COMPARISON OF 3',5'-LINKED AND 2',5'-LINKED DNA DUPLEX STABILITIES BYELECTROSPRAY-IONIZATION MASS-SPECTROMETRY, Chemical communications, (6), 1996, pp. 747-748
Two mutually complementary strands of 2',5'-linked DNA form. a unique
noncovalent complex observed by electrospray ionization mass spectrome
try; by the latter method, the double-stranded state of a 2',5'-linked
DNA duplex is less stable than the natural DNA duplex of identical ba
se composition.
