微型模式动物、模式植物、大体积细胞等在生命科学研究中有着非常广泛的应用,但是由于这些对象体积太大,普通的流式细胞仪的粒径尺寸一般在几十微米,难以对秀丽线虫、斑马鱼这样的大粒径模式生物进行分析和分选;手工镜下分选非常耗时耗力、效率低下、准确性难以保证。BioSorter 高通量分选系统是一款特殊设计的分选型流式细胞仪,流通室径向尺寸可达2000微米,可以对秀丽线虫、蚕卵、斑马鱼卵及幼鱼、果蝇等模式生物进行高通量、自动化的分析和分选。

BioSorter 高通量分选系统能够很大程度上提高了分选效率,完成大规模的样品分选工作,实现高通量分选。还可对多种数据进行分析,可以开展用传统实验手段难以开展的课题实验。

BioSorter 高通量分选系统在国际上有数百家实验室的成功应用案例,在很多知名期刊也有很多引用文献。该设备的应用,能够帮助实验室在很大程度上提高实验效率、拓展科研方法、缩短科研产出时间。

What’s new with COPAS?
In the most recent update of the COPAS platform we have upgraded the system electronics and this moved COPAS to the newer, friendlier, more powerful FlowPilot software suite. This change is denoted by the name COPAS FlowPilot, abbreviated as COPAS FP. In this new version the model names COPAS BIOSORT, SELECT, PLUS and XL have been replaced by the more meaningful COPAS FP-250, FP-500, FP-1000 and FP-2000.

The COPAS FP platform is designed for the measurement of objects ranging in size from 20–1500 microns (diameter). Each of the four COPAS FP models features a fixed, specially engineered fluidic path, flow cell and optics optimized for a specific subset of that size range to provide maximum speed, accuracy, resolution and throughput, depending on the application. Instruments can dispense objects either into bulk receptacles or multiwell plates.

A 488 nm solid state laser is used to measure both the size and optical density of the objects, as well as for fluorescence excitation. Each COPAS FP system can be equipped with up to three lasers.

The real-time analysis of these measured parameters is used to make sort decisions and only those objects meeting the user-selected sort criteria are gently dispensed into multiwell plates or stationary receptacles. Those objects not meeting the sort criteria are diverted by a puff of air to a sample recovery container, where they may be recaptured, unharmed and still viable.

Instruments are equipped with an X-Y stage to permit the dispensing of objects into micro-wells, including 24-, 48-, 96-, and 384-well plate formats. Using the FlowPilot™ software, users may custom design templates or use default templates.

Factory trained personnel will install your new COPAS FP system and train you at your site in the operation and routine maintenance of the system and accessories.

All systems are supplied with a Windows® workstation running FlowPilot™ software for operation and analysis.

Choosing a COPAS FP Model

Each COPAS FP system features a specially engineered fluidic path and flow cell optimized for a specific object size range to achieve the highest accuracy and sensitivity possible. The table shown at Choosing the Right Platform and Model summarizes the largest object size recommended for each COPAS FP model and also provides general system recommendations based on some sample applications. The applications listed are not exhaustive, but simply meant to provide a general overview of system capabilities. For a more detailed discussion of your particular application, including those applications that are not listed here, please contact our applications scientists directly at yuyan0317@126.com.
