Fluorescence Microscope Simulation of the Mitotic Spindle February 1, 2009 By John Sopko The mitotic spindle model (Yeh et al., 2008). (a) Side-on view; (b) end-on view. Helices represent the chromatin labeled with green fluorescing protein. Experimental and noise-free simulated images in side-on orientation (c-d) and end-on orientation (e-f). Differences in background between experimental and simulated images are caused by external chromatin not accounted for in the model. Structural variation in real specimens account for shape discrepancies. Comments are closed.
