| 摘要 |
The invention provides a method for determining a degree of phosphorylation of a substrate, for example a peptide substrate, using a fluorescence probe that acts alone or with another material and has a lifetime that varies when in proximity to a phosphate, the method comprising: causing the fluorescence probe to fluoresce; measuring a time response of the fluorescence, and analysing the fluorescence time response to identify a fluorescence component having a lifetime associated with phosphorylated substrate and a fluorescence component having a lifetime associated with un-phosphorylated substrate. |
