How are images obtained with standard fluorescence microscopy different from those obtained with confocal laser-scanning microscopy (CLSM)?
- They have higher spatial resolution in CLSM images.
- CLSM captures images at a lower magnification than standard fluorescence microscopy.
- CLSM excludes out-of-focus fluorescence from the specimen. (correct)
- Standard fluorescence microscopy captures more dynamic processes than CLSM.
