Adaptive optics easy3D STED enables deep imaging of cleared adult kidney samples
Comparison of a XZ-slice deep into a renal corpuscle using conventional 3D STED imaging and an easy3D STED imaging. easy3D allowed imaging up to 80 µm into cleared rat kidney tissue using an oil objective. Without adaptive optics, the mismatch between immersion oil and sample leads to complete signal loss.

Abberior LIVE 580 活细胞超分辨成像应用的染剂
live-cell dyes. The striking feature of this dye series is their cell permeability, enabling live-cell experiments. The LIVE dye series offers unique labeling options - live-cell imaging with organic dyes now becomes possible! The LIVE dyes combine the best of two worlds:
- organic dyes with the highest brightness & photostability among all fluorescent markers, and
- live-cell labeling out of the box.
