| In Vitro | Calcein accumulates intracellularly in coelomocytes incubated in coelomic fluid or ISO-EDTA. Coelomocytes incubated in CF show an increase in the calcein fluorescence intensity compared to the control. |
| Cell Assay | Coelomocytes suspensions (ISO and CF) are separately incubated with calcein-AM (excitation and emission wavelength: 496 nm and 516 nm, respectively) at a final concentration of 200 nM, during 30 min, at 26°C. Calcein-AM is a nonfluorescent ABC transporter substrate whose intracellular accumulation is inversely proportional to ABC transporter activity. Intracellular esterases convert calcein-AM into the fluorescent dye calcein, which is not an ABC transporter substrate, thereby accumulating the dye inside the cell. Therefore, a high fluorescence signal indicates low ABC transporter activity whereas a low fluorescence signal indicates high activity. The fluorescence of samples is measured by flow cytometer. The experiment is repeated six times in duplicates. |
