What are optically controlled substances?
Optically controlled substances are compounds that can be activated or deactivated using light, allowing for precise control in biological experiments.
How does flow cytometry work?
Flow cytometry is a technique used to analyze the physical and chemical characteristics of cells or particles as they flow in a fluid stream through a beam of light.
What is the significance of combining optogenetics with flow cytometry?
Combining these techniques allows researchers to study dynamic cellular processes in real time, enhancing our understanding of cell signaling.
What type of cells were used in this study?
The study used transduced Ramos B lymphocytes for the experiments.
