===Autophagy===
*[[LY-294002]]


10. Add de-jellying solution to eggs, intermittently swirling gently.  De-jellying takes 5-10 minutes.  After they are dejellyed, there volume will decrease up to five fold and they will pack much tighter.

*[[etoposide]]
*[[Hydroxyurea]]


15. Transfer eggs to a 2.2 ml thin, clear plastic centrifuge tube containing 2 ml of LPC and 10 ml of cytochalasin B.  The size of the tube depends on the number of eggs collect.  For lower numbers of eggs, use a smaller tube. 
===DNA Synthesis===

23. After wiping the outside of the tube with a alcohol wetted kimwipe, insert an 18-gauge needle into the side of the tube (BE CAREFUL), and draw out the cytoplasmic layer.  Use a new needle for each tube.

===Small GTPases===


26. Test to determine if the extract is arrested in mitosis.  To do so, take 15 mL of fresh extract and to a tube that contains 1 ml of diluted sperm for experiment.  Remove 7.5 ml and add to a tube containing 1 ml of 4 mM CaCl2.  Place at room temperature for 20-30 minutes. 


27. Place 1 ul of extract onto a plane glass slide and overlay with 3 ml of extract fix (100 ml 10x MMR, 0.1 ml Hoechst, 300 ml 37% formaldehyde, 600 ml of 80% Glycerol).  Examine under the microscope.  The sample containing calcium should exit mitosis and have interphase looking nuclei (rounded morphology). The sample without calcium should remain in mitosis and contain condensed mitotic chromatin.
