1. Transfer 50 ml of embryo cultures to centrifuge tubes. Spin at 1500 rpm for 5 minutes. Check that you can see a pellet of embryos at the bottom.Quickly pour off the ASW. Try to remove as much as possible, but don't worry about a little ASW left in the tube.2. Gently swirl tube to resuspend the embryos. Add 40 ml of ice cold methanol and allow to fix on ice for no more than 20 min. By this time, the embryo......阅读全文
