From: Slow, stochastic transgene repression with properties of a timer
GFP fluorescence of clones 5, 6, and 18 with antibiotic selection or pre-sorted cells with repressed levels of GFP. Levels of GFP fluorescence by (a) cultures grown with puromycin and (b) cultures started with cells producing low or no fluorescence (no error bars because n = 1). Fraction of cells are shown with high (diamonds), low (squares), or no (triangles) fluorescence.
