NRK-EGFP-H2B Cells

The NRK-EGFP-H2B cell line is a genetically modified variant of normal rat kidney (NRK) cells that stably express the enhanced green fluorescent protein (EGFP) fused to histone H2B. This modification allows for real-time visualization of chromatin and nuclear dynamics, making this cell line an invaluable tool for studying cell cycle progression, mitosis, and chromatin organization. The stable expression of EGFP-H2B provides a bright and consistent fluorescent signal, facilitating high-resolution live-cell imaging and enabling researchers to monitor nuclear events with great precision. NRK cells, originating from the kidney tissue of an adult rat, are widely used in cellular biology due to their robust growth characteristics and well-documented physiological behaviors. The introduction of the EGFP-H2B fusion protein into these cells does not significantly alter their growth or morphology, allowing for reliable and reproducible experimental conditions. This cell line is particularly useful in studies of kidney cell biology, cellular responses to stress, and mechanisms of carcinogenesis, given the kidney's role in filtering blood and excreting waste. Additionally, the fluorescence capabilities of NRK-EGFP-H2B cells can be harnessed in drug screening applications to observe drug effects on cell proliferation and nuclear morphology in real-time.
