Ovaries from 2- to 3-day-old yeasted females were dissected and fixed with cacodylate/formaldehyde as described by Hughes et al. (2011) (link). For embryos, mated females laid on grape plates for 2 h, and then embryos were fixed in heptane/methanol as described by Bonner et al. (2013) (link). Rat anti-α-tublin primary antibody (1:250, BioRad) was used with Alexa-488 or Alexa-555 conjugated secondary antibody (Molecular Probes, 1:350). DNA was then labeled with DAPI (2 μg/ml), and samples were mounted in ProLong Gold (Invitrogen).
For all imaging, the DeltaVision microscopy system (Applied Precision), equipped with an inverted Olympus 1670 microscope and a high-resolution CCD camera, was used. All acquired images were then deconvolved using SoftWoRx software (Applied Precision).
