【摘要】 ２－氨基乙磺酸类似物乙醛磺酸（ＳＡＤ）具有荧光（ＥＸ：３１４ｎｍ；ＥＭ：４００ｎｍ）。ＳＡＤ与ＡＴＰ反应过程中醛基减少的时间动力学表明，ＡＴＰ在３７℃经过４小时可能完全与ＳＡＤ反应。ＳＡＤ与ＡＴＰ反应的结果可使ＡＴＰ的荧光增强约一倍。以上结果表明：ＳＡＤ可以在上述温和条件下与ＡＴＰ进行反应，因此，ＳＡＤ可能成为一种ＤＮＡ和ＲＮＡ的修饰或调节分子。更多还原

【Abstract】 Sulfonic aldehyde (SAD) fluoresces at 400 nm by excitation at 314nm. The fluorescence de pends on strong acidic condition (<pH3.0). The ATP fluorescence increased after its reactionwith SAD in double distilled water. Mcasurements of the aldehyde group withdinitrophenyl-hydrozine showed that the SAD may react completely with ATP in 4 to 5h.It appears that SAD may be used as a modifier of DNA and RNA, and a regulator of DNAexpression as well.更多还原
