calcein

Calcein (Fluorexon) 是一种荧光染料和自灭探针，是一种脂囊泡渗漏的指示剂，也是一种 EDTA 钙离子滴定和荧光测定钙离子的络合指示剂。

Calceincalcium potassium 是 Calcein 的钙钾盐形式。这种化合物是一种荧光染料和自灭探针，用于作为脂囊泡渗漏的指示剂，并可用于 EDTA 钙离子的滴定和作为荧光测定钙离子的络合指示剂。此外，Calceincalcium potassium 还可以作为模型药物，评估药物递送系统的效率和生物利用度。

Calcein Blue AM 是一种可以透过细胞膜的活细胞标记染料。 进入细胞后，细胞内的酯酶切割乙酰氧基甲基 (AM) 的酯基，产生无法透过细胞膜的 Calcein Blue 荧光染料。

Calcein Orange Diacetate is a fluorogenic dye that is used to assess cell viability. It is hydrolyzed to the fluorescent probe Calcein Orange . Calcein Orange is retained by living cells and displays excitation/emission maxima of 525/550 nm, respectively. Calcein Orange Diacetate is an orange-emitting variant of the green fluorophore Calcein AM , which has been used to evaluate cell viability and cytotoxicity.

Calcein Red AM作为绿色荧光探针Calcein AM的红色发射衍生物，是一种细胞膜通透性非荧光乙酰甲氧酯化合物，广泛应用于细胞活力与毒性评估。经细胞内酯酶水解后产生的荧光产物滞留于活细胞，在560 nm激发波长与574 nm发射波长处呈现特征荧光峰。

Calcein-AM (Calcein acetoxymethyl ester)是一种可渗透进入细胞、常用于测定真核细胞活力或线粒体通透性转换孔的绿色荧光探针，自身无荧光，被水解后发绿色荧光，激发/发射波长：494/515 nm。

Calcein tetraethyl ester是一种Calcein衍生物,是合成Calcein AM的中间体。Calcein是一种荧光染料和自灭探针，是脂囊泡渗漏的指示剂，也是EDTA 钙离子滴定和荧光测定钙离子的络合指示剂。

Calcein Blue 是含有亚氨基二乙酸结构的香豆素衍生物，是不渗透膜的荧光染料，也是金属荧光变色指示剂。

CytoCalcein Violet 450 is a fluorogenic dye used to assess cell viability. It is a cell-permeable dye that, upon entering cells, is cleaved by intracellular esterases. CytoCalcein Violet 450 is retained by living cells and displays excitation/emission maxima of 405/450 nm, respectively.

CytoCalcein Violet 500 is a fluorogenic dye used to assess cell viability. It is a cell-permeable dye that, upon entering cells, is cleaved by intracellular esterases. CytoCalcein Violet 500 is retained by living cells and displays excitation/emission maxima of 405/500 nm, respectively.
