Title
Time-lapse and z-series images of H2B-SNAP and the tdTomato-CENPC in aged mouse oocyte
Description
Time-lapse and z-series images of H2B-SNAP and the kinetochore marker tdTomato-CENPC from prometaphase to anaphase of 16 to 22 month-old-mouse oocyte. The images of chromosome 1 and chromosome 18 at a at a certain time during imaging were reposited as DE_2_W000x_P001_T0yyy.lsm file.

Description
From prometaphase to anaphase oocyte from 16 to 22 month-old-mouse, in which chromosomes and kinetochores were visualized.
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.

Visualization Method
H2B with SNAP-tag was visuallised with SNAP-Cell 647-SiR. To visualize kinetochores, centromere
protein C was tagged with tdTomato. Chromosome1 and Chromosome18 were visualized with BFP and mClover respectively.
