Analysis of fluorescent protein expressing cells by flow cytometry.

ABSTRACT

The process for transfection of cells with expression and gene-trap vectors expressing fluorescent reporter proteins is described. The measurement and sorting of discrete populations of transfected cells is also described and illustrated. Of particular importance, the maintenance of stability may be important and a simple strategy to monitor this has been developed. Finally, an effective method for improving the ability to measure low-level fluorescence from autofluorescence is described.
