Sampling Device for High-Throughput Light-Sheet-Based Microscopy


Light-sheet-based fluorescence microscopy (LSFM) is a powerful method to analyze 3D living or fixed biological samples - such as cell cultures, embryos, or tissue - with high temporal resolution. The novel sampling device facilitates high-throughput LSFM measurements without loss of imaging quality.


Light-sheet-based fluorescence microscopy (LSFM) is an extremely efficient light-optical tool to monitor 3D fluorophore distributions in biological samples. In comparison to state-of-the-art, e.g. confocal, fluorescence microscopy, the light-induced stress is reduced by orders of magnitude. Hence, LSFM is especially suited for imaging of sensitive specimen, living tissue, or living plants over long periods of time. In addition, the method provides a high imaging speed and an exceptional resolution of fixed and cleared probes. However, similarly to inverted microscopy, most LSFM setups require a non-planar positioning of the sample. Hence most commercially available LSFM setups are limited in their application for cell-based high-throughput screenings.

The novel sampling device, which may be combined with standard multi-well plates, was developed to facilitate high-throughput screenings of biological probes such as multicellular spheroid cultures. This is achieved by position-ing of the lighting source and the detection device below and at 45° angles to the sample. By introducing a customized zigzag shape of the microtiter plate (see figure) the lens distance is minimized facilitating selection of matching lenses. In addition, a novel holder has been developed mounting both lenses, which can be rotated around its axis and tilted. Hence, lenses with smaller working distances and larger diameters can be employed. Due to the rotation, different perspectives can be obtained. By employing identical lenses for excitation and detection these functions are interchangeable by rotation of the mirrors further accelerating the imaging process. The novel setup allows for an accelerated - thus both time- and cost-efficient - throughput compared to standard LSFM measurements.
