Rare Earth Ion Mediated Fluorescence Accumulation on a Single Microbead: An Ultrasensitive Strategy for the Detection of Protein Kinase Activity at the Single-Cell Level

Recent Progress in Fluorescent Chemosensors for Protein Kinases

Protein kinases are involved in almost all biological activities. The activities of different kinases reflect the normal or abnormal status of the human body. Therefore, detecting the activities of different kinases is important for disease diagnosis and drug discovery. Fluorescent probes offer opportunities for studying kinase behaviors at different times and spatial locations. In this review, we summarize different kinds of fluorescent chemosensors that have been used to detect the activities of many different kinases.

Lanmodulin Remains Unfold and Fails to Interact with Lanthanide Ions in Escherichia coli Cells

We report the conformation of a newly discovered specific lanthanide ions (Ln3+) binding protein, Lanmodulin (LanM), and its inteaction with Ln3+ in Escherichia coli cells using In-cell NMR. We found...
