20110118142 | DUAL LABELING METHODS FOR MEASURING CELLULAR PROLIFERATION - The present invention provides a method for measuring cellular nascent nucleic acid synthesis by dual pulse labeling of nucleic acid. The first pulse labeling of nucleic acid with a nucleoside analog allows establishment of a baseline nucleic acid synthesis rate. Pulse labeling of the nucleic acid with a second nucleoside analog then allows measurement of any changes to nucleic acid synthesis. The nucleic acid synthesis can be measured as cell proliferation, DNA, or gene expression, RNA. This method does not require a potentially artifact-inducing intermediary wash step between pulse labels. Additionally, this method may be used to screen compounds for their affect on cellular proliferation by treating cells or an organism with the test compound simultaneous to or before treatment with a competitive nucleoside analog. | 05-19-2011 |
