Sol–gel/diaminobenzoic acid hybrid materials were also generated to be used as the MALDI matrices for the analysis of oligonucleotides. It is because that DABAs have good molar absorptivity at wavelength of 337 nm. Furthermore, two amino functional groups attached to the aromatic ring in DABAs can also suppress the cation adductions of oligonucleotides and leave the protons to the oligonucleotides during MALDI-MS analysis. This matrix system can be used as an alternative for the analysis of oligonucleotides.

本論文也利用雙胺基苯甲酸與溶膠凝膠混成產(chǎn)物當做MALDI基質(zhì)來分析DNA分子久久精品囯产99精品亚洲，利用雙胺基苯甲酸本身具有吸收雷射的特性欧美二级，且其含胺之官能基可和鈉、鉀離子競爭DNA上磷酸根的負離子結(jié)合部位超级乱婬Av片无码，因此可和DNA有較強的親合力日韩丝袜在线精品视频在线，而在脫附游離的過程中并可轉(zhuǎn)移質(zhì)子給磷酸根，可有效降低鹽類的干擾国产又黄又粗又长的视频，此一基質(zhì)系統(tǒng)可取代傳統(tǒng)MALDI基質(zhì)混合胺鹽的效果91看电影亚洲精品，適合用於DNA樣品的分析。
