Background

CFDA-SE (Carboxyfluorescein diacetate succinimidyl ester; CAS: 150347-59-4) is a membrane-permeant fluorescent dye commonly utilized for labeling viable cells and monitoring cellular proliferation. Upon entering cells, intracellular esterases hydrolyze CFDA-SE into carboxyfluorescein succinimidyl ester (CFSE), which becomes fluorescent (excitation 494 nm, emission 521 nm), binds covalently to intracellular amino groups, and is thereafter trapped within the cell cytoplasm. Each cell division results in halving fluorescence intensity, enabling accurate quantification of successive proliferation events via flow cytometry. CFDA-SE labeling methodology has extensive applications in assessing lymphocyte, fibroblast, NK cell, and bacterial proliferation both in vitro and in vivo.

Protocol

Cell experiment:[1]

Cell lines

Human erythroleukaemic cell line K562, mouse lymphoma cell line YAC-1, human mammary cancer cell line MCF-7 and human melanoma cell line A375

Reaction Conditions

1, 1.5, 2, 2.5, 5 and 10 µM CFDA-SE

Applications

CFDA-SE at 2.5 μM stained more than 95% of the cells on all cell lines tested, and dose-dependently increased fluorescence intensity of stained cells. The optimal concentration for K562 and YAC-1 was found to be 2.5 μM, while the optimal concentrations for A375 and MCF-7 were found to be 5 μM and 10 μM, respectively. Within the 6 h experiment period, no cytotoxicity related to CFDA-SE was observed.

Animal experiment:[4]

Animal models

C57BL/6 mice, aged 5 ~ 8 weeks

Dosage form

10 μM

Injected into thymic lobe

Applications

CFDA-SE, at 80 times the concentration used for in vitro labeling, was nontoxic and labeled randomly approximately 15% of thymocytes 24 h after injection. The turnover rate of labeled thymic emigrants in the lymph nodes was in the order of 21 days. Thus, CFDA-SE may serve as a powerful tool in relatively long-term migration studies.
