Copas Biosort

The Copas Biosort is an automated flow-based instrument that measures, analyzes, and sorts large biological specimens, such as nematodes, embryos, and cell aggregates, according to their physical and fluorescent properties. Samples pass individually through a fluid-filled detection system, where optical signals such as time of flight and extinction are recorded alongside fluorescence; user-defined gates then direct selected specimens into collection vessels. By enabling rapid, consistent phenotypic screening and separation, the Copas Biosort supports applications in developmental biology, genetics, toxicology, and drug discovery, while reducing manual handling and improving the scale and reproducibility of biological experiments.

2012

We describe a protocol using C. elegans and RNAi feeding libraries that allows automated measurement of multiple parameters such as fluorescence, size and opacity of individual worms in a population. We give one example of a screen to identify genes involved in anti-fungal innate immunity in C. elegans.

Liquid-grown Streptomyces cultures are characterized by mycelial pellets that are heterogeneous in size. We here describe a method to analyze and sort such pellets in a high-throughput manner. These pellets can be used for further analyses, which will provide leads to understand and control growth heterogeneity.

2007

Micro-dissection of rat brain into various regions is extremely important for the study of different neurodegenerative diseases. This video demonstrates micro-dissection of four major brain regions include olfactory bulb, frontal cortex, striatum and hippocampus in fresh rat brain tissue. Useful tips for quick removal of respective regions to avoid RNA and protein degradation of the tissue are given.
