Title
Time-lapse and z-series images of H2B-SNAP and the tdTomato-CENPC in young mouse oocyte
Description
Time-lapse and z-series images of H2B-SNAP and the kinetochore marker tdTomato-CENPC from prometaphase to anaphase of 7 to 9 week-old-mouse oocyte. Both of xyzt-images and xyt-image (z-stacked images) were reposited.

Extrinsic Variable
To visualize chromosomes and kinetochores, in vitro transcribed mRNAs for H2B-SNAP and tdTomato-CENPC (centromere protein C) were injected. To detect chromosome1 and chromosome18, MCP-3tagBFP and PCP-3mClover were also introduced for CRISPR-Sirius method.
