| 摘要 |
The invention described herein features infrared fluorescent protease reporters (iProteases) and methods of use thereof. The iProteases can be used in in vivo and in vitro assays to detect protease activity and disease states associated with protease activity. In a still further embodiment, the present invention provides a kit comprising any of the above described polynucleotides. In a further aspect, the present invention provides a method of in vivo optical imaging. In a still further embodiment, the in vivo imaging is performed in a living animal. In a further aspect, the present invention provides a method of detecting protease activity, the method comprising expressing a polypeptide according to any of those described above in a cell. |
