In march 2009 we obtained the new BD ARIA II, which not only allows 14 parameter flow cytometry, but also sorting of even very small antigen specific T cell subpopulations for further molecular analysis in close collaboration with Pierre Coulie´s group in Brussels. [PhD student Steve Voland]

This FACS analyser that is available to us is used, e.g., for the analysis of dendritic cells.

We have a FACS Aria cell sorter at our disposition from BD Biosciences (URL: http://www.bdbiosciences.com/features/products/display_product.php?keyID=53). We used this FACS Aria among other things for fluorescence activated cell sorting for proteomic investigations. Using Fluorescence activated cell sorting allowed us to obtain highly pure fractions of CD8+, CD4+ and DN DC subsets. However, because DC are a very rare population, this method is very material- and cost-intensive. Furthermore, it is not surprising that the obtained cell numbers of each subset after isola...
