| 摘要 |
The present invention relates to a method for determination of an analyte in a cell by fluorescent correlation spectroscopy. Luminescent labels are attached to receptors, which may be nucleic acids. the receptors are capable of hybridising with an analyte, which may be a DNA or RNA molecule. According to the invention, the receptors are introduced into living cells to interact with the analytes.
This interaction is monitored by fluorescent correlation spectroscopy. The method of the invention may be used for direct gene expression analysis.
