Figure 1 DNA fragmentation analysis of mouse oocytes based on the length of the comet tail (magnifications, ×400). (a) Fresh in vivo-matured oocyte. (b) Fresh in vitro-matured oocyte. (c) Vitrification of in vivo-matured oocyte. (d) Vitrification of in vitro-matured oocyte. The direction of electrophoresis was from left to right and the comet tail containing the DNA fragments was stained by ethidium bromide. Scale bar, 100 μm.
