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.

Intrinsic Variable

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.
