Research Abstract |
In order to visualize dynamics of inactive X chromosome, we developed two methods monitoring histone modifications in living cells. The first method uses fluorescently labeled antigen-binding fragment (Fab), which binds to endogenous modifications when loaded into living cells. Using this technique, we were able to track the behavior of inactive X chromosomes, where trimethylated histone H3K27me3 is enriched, during the cell cycle. The second method is a genetically encoded system using a single-chain variable fragment tagged with the green fluorescent protein. These methods will be useful to track epigenetic changes during development and differentiation.
