| 摘 要： | Positive ion ESI-MS has been used to examine the fragmentation pathways of the complex ions of deoxydinucleotides with H^ ,Na^ ,K^ by LCQ instrument.It had been found that the dissociation Varied markedly due to the differences of the base sequence.The alkali-metal ion binding site and the charcaterization of dissociation were directed by the size of metal ion,the sequesce of base and the steric hindrance.

| Abstract: | Positive ion ESI-MS has been used to examine the fragmentation pathways of the complex ions of deoxydinucleotides with H+, Na+, K+ by LCQ instrument. It had been found that the dissociation varied markedly due to the differences of the base sequence. The alkali-metal ion binding site and the characterization of dissociation were directed by the size of metal ion, the sequence of base and the steric hindrance. |
