Abstract |
This chapter describes a straightforward method for isolating glioblastoma stem cells (GSCs) from in vitro tissue cultures via fluorescence-activated cell sorting (FACS) using CD133 as a surface marker. The use of a directly conjugated antibody to an APC fluorophore against the CD133 molecule provides sufficient and clear detection of positive cells from the rest of the population. This strategy avoids an unnecessary secondary antibody incubation step thereby minimizing loss and increasing yield. The same protocol can be applied to other GSC surface markers. The described method allows for quick and efficient purification of GSCs, which can then be used in several downstream applications. |
