Calcein (Synonyms: 钙黄绿素; Fluorexon)
Calcein (Synonyms: 钙黄绿素; Fluorexon)
生物活性 | Calcein is a fluorescent dye and self-quenching probe, used as an indicator of lipid vesicle leakage, and also as a complexometric indicator for titration of calcium ions with EDTA, and for fluorometric determination of calcium. | ||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|
体外研究 (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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||
