| 描述： |
CFSE Cell Proliferation Kit provides convenient single-use vials for cell labeling. CFSE [5-(and 6)-carboxy fluorescein diacetate, succinimidyl ester] is a fluorescent tracer that diffuses passively into cells and covalently labels intracellular proteins, resulting in long term cell labeling. It is non-fluorescent but becomes brightly green fluorescent once it is hydrolyzed by intracellular esterases in viable cells. After hydrolysis, the succinimidyl ester group reacts with intracellular amines forming fluorescent conjugates that are retained in the cells. The excess unconjugated CFSE diffuses passively back to the extracelluar medium and can be rinsed away. After labeling, cells can be fixed with formaldehyde or gluteraldehyde. The kit is used for in vitro and in vivo labeling of cells to trace multiple generations using dye dilution by flow cytometry. |

成功案例
Cell generation analysis with CFSE Cell Proliferation Kit. Jurkat cells (~1×106 cells/ml) were stained with CFSE dye (1 µM) on Day 0. The cells were cultured for 7 days. Fluorescence intensity was measured with FACS flow cytometer.
