METHODS AND COMPOSITIONS FOR SELECTIVE DETECTION OF HOMOCYSTEINE

摘要

Compositions and methods have been developed for the detection of homocysteine. For example, a fluorescent probe can selectively detect homocysteine based on the redox reaction between the azido group and homocysteine. The fluorescent response is selective for homocysteine over other biologically abundant thiols such as cysteine and glutathione. In addition, a linear calibration curve can be obtained for quantitative analysis in phosphate buffer and plasma.
