The cells were then sorted by fluorescence-activated cell sorting (FACS) on the basis of E/nestin- or P/musashi1-driven GFP expression. Both P/musashi1:hGFP- and E/nestin:EGFP-sorted cells were ...

based on their EGFP:DsRed ratios. They determined the distribution of each open reading frame across the FACS fractions using a DNA microarray. Using this distribution they calculated a protein ...
