HK EGFP-Kleisin-beta Cells

The HK EGFP-Kleisin-beta cell line represents a genetically modified variant of Hela Kyoto cells designed primarily for the study of chromosome cohesion during the cell cycle. This cell line expresses an enhanced green fluorescent protein (EGFP) fused with the Kleisin-beta protein, a crucial component of the cohesin complex that is vital for sister chromatid cohesion. The expression of EGFP-tagged Kleisin-beta allows for real-time visualization of cohesin dynamics and localization throughout the cell cycle, facilitating detailed analyses of chromosome structure and function in a cellular context. This cell model is typically utilized in research focusing on the mechanisms of mitotic and meiotic chromosome segregation, particularly looking at how cohesin's regulation influences genetic stability and cell division. The fluorescent tagging of Kleisin-beta enables the investigation of its interaction with other cohesin components and chromosomal proteins, providing insights into the spatial and temporal assembly of cohesin on chromosomes. The use of this cell line extends to studies of genetic disorders and cancers where cohesin function is disrupted, offering a valuable tool for understanding pathogenesis and developing therapeutic strategies.
