Figure 1From: Master equation simulation analysis of immunostained Bicoid morphogen gradientBicoid profile from FlyEx embryo ms18 after background removal. (A) The spatial index j (μ m/5) is the index of 5 μ m bins. The fluorescence intensity I j (circles) were fit to an exponential F[I j ] = a exp(-j/λ) (solid line) with two scaling index lines 1.5F[I j ] and 0.5F[I j ] (dashed). The fluorescence intensity were then converted into log scale in panel (B).Back to article page
