 ===== System overview ===== ===== System overview =====
-{{  :cell_analyzers.png?​0x300|}} The BD LSRFortessa 1 //cell analyzer// ​is a benchtop ​digital ​flow cytometer equipped with a fixed-alignment flow cell that is gel-coupled ​to the collection optics. It has three spatially separated ​lasers - 405 nm, 488 nm and 640 nm. Its primary function is to characterize complex populations of cellsIndividual cells pass single file through ​streamwhich is interrogated ​by the three lasers with the emitted ​light being detected ​by photomultiplier ​(PMTtubes. The system electronics calculates ​the time it takes single cell to pass through each laser intercept ​and assigns the signal ​of each PMT to the appropriate cell. Besides fluorescence, the physical properties of the cell are also analyzed ​with side scatter (SSC), which reflects ​the internal complexity ​of a cell and forward scatter (FSC), which is roughly proportional to cell size. The sample flow rate can be set to lowmedium and high values, which correspond approximately ​to 12, 35 and 60 μl/minute, respectively. If your cells are stained with PerCP-Cy5.5 or you need high-throughput samplercheck the [[bd_lsr_fortessa_2|BD LSRFortessa 2]] instead. If you need multicolor ​analysis of up to 16 parameterscheck the [[bd_lsr_fortessa_x20|BD LSRFortessa X-20]].+{{  :how_the_imagestream_works.png?​0x300|}} The Amnis ImageStreamX ​is a benchtop ​multispectral //​imaging ​flow cytometer// equipped with two CCD cameras ​that can acquire up to 12 images simultaneously of each cell or object in brightfield,​ scatter and multiple fluorescent channels at rates up to 5000 objects/sec. It has five lasers - 375 nm, 488 nm, 561 nm, 642 nm and 785 nm (dedicated ​to side scatter)Cells in suspension are hydrodynamically focused in flow cellwhere they are illuminated ​by a brightfield ​light source and by lasers. High numerical aperture ​(NAobjective lenses collect fluorescence emission, as well as scattered and transmitted light from the cells which then intersect ​spectral decomposition element that focus different spectral bands on different physical locations of two CCD cameras. By collecting large numbers of digital images per sample ​and providing numerical representation ​of image-based features, the ImageStreamX combines single ​cell standard microscopy information ​with the statistical significance ​of large sample ​sizes in standard ​flow cytometry. While you can use it to measure fluorescence intensity as in conventional flow cytometersthe best applications for the ImageStreamX take advantage of its imaging abilities ​to locate ​and quantify the distribution of signals within ​cells or even between cells in cell conjugatesThe system also has dedicated software application used for spectral compensationimage analysis and statistical ​analysis of acquired images (IDEAS) with predefined wizards for apoptosiscell cycle, co-localization,​ internalization,​ shape change, spot counting and others.
