The present invention relates in general to cellular analysis tools and more particularly to methods and systems for detecting or determining cyclic nucleotide concentrations and related pathway activation in samples. Samples containing cyclic nucleotides may be contacted with a cyclic nucleotide-dependent protein kinase (e.g., cAMP- and cGMP-dependent protein kinases) and a detection system that includes a substrate capable of being phosphorylated by the cyclic nucleotide-dependent protein kinase. The activity of cyclic nucleotide related cell signaling pathways may be measured based on detecting the activity of the cyclic nucleotide-dependent protein kinase.
本发明总体上涉及细胞分析工具,更具体地说,涉及检测或确定样品中环核苷酸浓度及相关途径活化的方法和系统。含有环核苷酸的样品可与环核苷酸依赖性蛋白激酶(如 cAMP 和 cGMP 依赖性蛋白激酶)和检测系统接触,检测系统包括能被环核苷酸依赖性蛋白激酶磷酸化的底物。环核苷酸相关细胞信号通路的活性可根据检测环核苷酸依赖性蛋白激酶的活性来测量。
