5-Carboxyfluorescein diacetate succinimidyl ester | CAS 150206-05-6

5-Carboxyfluorescein diacetate succinimidyl ester (CFSE), a renowned fluorescent dye in biological research, boasts a myriad of applications in scientific exploration. Here are four key uses of CFSE:

Cell Proliferation Studies: Delving into the intricate dynamics of cell division, CFSE seamlessly integrates into the cytoplasm of cells, dividing equally among progeny cells as the cell division process unfolds. This unique property enables researchers to meticulously track proliferation across multiple generations, offering invaluable insights to the fields of immunology, cancer research, and developmental biology.

Flow Cytometry: Harnessing the power of CFSE in flow cytometry, scientists can accurately label and analyze live cells based on their varying fluorescence intensities. This cutting-edge tool streamlines the differentiation of cell populations, assessment of cell viability, and measurement of crucial cellular processes such as apoptosis. Phenotyping cells and exploring their functional attributes are significantly enhanced through the utilization of this sophisticated technique.

Cell Migration Studies: With the aid of CFSE labeling in migration assays, researchers are granted a visual and quantitative window into the intricate dynamics of cell movement. By closely monitoring the nuances of fluorescent signals, the complexities of cell migration in response to diverse stimuli or fluctuating environments are unveiled. This avenue of study sheds light on critical processes like wound healing, cancer metastasis, and immune cell trafficking, unraveling the mysteries of cellular locomotion.

Intracellular Dye Transfer Assays: Leveraging CFSE in cell-to-cell dye transfer assays offers a unique opportunity to delve into the intricate interactions and communication patterns between cells. The transfer of dye from a labeled cell to an unlabeled counterpart signifies physical contact or cellular communication, providing a unique insight into events like immune synapse formation and gap junction communication, elucidating the intricacies of cellular dialogues.
