药物结合热的第一组测量 柔红霉素对DNA的作用在10-20微摩尔范围内(其中 以单体形式为主)已经被制造出来。这些结果是 在1988年世界银行会议上的一次海报会议上提交 生物物理学会。在这些浓度下的热焓是 在30-50微焦耳范围内。随着钽的停止流动 量热计,我们每天能够测量到120个这样的反应 其不确定度仅为3微焦耳。我们预计还会有两个人 探索盐和温度依赖关系的一系列实验 热焓的变化。这些实验是在 与罗格斯大学化学系合作 大学。
英文摘要
The first set of measurements of the drug binding enthalpies for daunomycin to DNA in the 10-20 micromolar range (where the monomeric form predominates) have been made. These results were presented in a poster session at the 1988 meeting of the Biophysical Society. The enthalpies at these concentrations were in the 30-50 microjoule range. With a tantalum stopped flow calorimeter, we were able to measure 120 of these reactions per day with an uncertainty of only 3 microjoules. We anticipate two more sets of experiments to explore the salt and temperature dependence of the enthalpies. The experiments are being performed in collaboration with the Department of Chemistry at Rutgers University.
