微型模式動物、模式植物、大體積細(xì)胞等在生命科學(xué)研究中有著非常廣泛的應(yīng)用,但是由于這些對象體積太大,普通的流式細(xì)胞儀的粒徑尺寸一般在幾十微米,難以對秀麗線蟲、斑馬魚這樣的大粒徑模式生物進(jìn)行分析和分選;手工鏡下分選非常耗時耗力、效率低下、準(zhǔn)確性難以保證。COPAS高通量分選系統(tǒng)是一款特殊設(shè)計的分選型流式細(xì)胞儀,流通室徑向尺寸可達(dá)2000微米,可以對秀麗線蟲、蠶卵、斑馬魚卵及幼魚、果蠅等模式生物進(jìn)行高通量、自動化的分析和分選。

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 In this new version the model names COPAS BIOSORT, SELECT, PLUS and XL have been replaced by the more meaningful COPAS FP-250, FP-500, FP-1000 and FP-2000.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.
