• To accelerate the discovery of proteins involved in Golgi structure and function.

Main Methods:

• Development of a correlative screening microscopy system.
• Integration of wide-field microscopy for rapid data acquisition.
• Application of dual-color direct stochastic optical reconstruction microscopy (dSTORM) for high-resolution imaging.
• Simultaneous imaging of cis- and trans-Golgi network alterations.

Main Results:

• Successful establishment of a correlative screening microscopy system.
• Demonstration of simultaneous capture and differentiation of Golgi network changes.
• Analysis of protein depletion effects on Golgi structure and function.

Conclusions:

• Correlative screening microscopy significantly speeds up the functional characterization of Golgi regulators.
