PALM Super-Resolution Imaging Experiments Based on Low-Noise sCMOS Cameras

This experiment adopts a TIRF illumination system paired with the low-noise Gloria 6504 sCMOS camera to efficiently capture single-molecule fluorescence signals from GFP-labeled adherent cells. A large number of single-molecule fluorescence events with stochastic blinking characteristics are recorded.

The acquired experimental data features low background, well-separated single molecules, high signal-to-noise ratio (SNR), and stable PSF profiles, meeting the data quality requirements for subsequent single-molecule localization and image reconstruction.

Benefiting from its advantages in pixel density, readout noise, frame rate and spatial sampling, the sCMOS camera shows promising potential outperforming conventional EMCCD cameras in single-molecule fluorescence research.

For cell biology studies including membrane protein organization, receptor clustering, and near-membrane signal transduction, the TIRF-sCMOS-PALM workflow serves as a robust tool for single-molecule and super-resolution imaging.
