Calcein

Calcein (Fluorexon) is a fluorescent dye and self-quenching probe used as an indicator of lipid vesicle leakage, a complexometric indicator for titration of calcium ions with EDTA, and for the fluorometric determination of calcium.

Calcein-AM (Calcein acetoxymethyl ester) is a cell-permeable green fluorescent probe commonly used for assessing eukaryotic cell viability or mitochondrial permeability transition pore, with no fluorescence itself. After hydrolysis, it emits green fluorescence with excitation emission wavelengths: 494 515 nm.

Calcein tetraethyl ester, a fluorescent dye, is utilized in biological studies for its ability to penetrate cellular membranes into living cells. This property renders it valuable for assessing cell viability and short-term cell labeling.

Calcein Blue is a blue-fluorescent, short-term dye.

Calcein calcium potassium is the calcium potassium salt form of Calcein. It serves as a fluorescent dye and self-quenching probe, useful as an indicator for liposome leakage and as a complexometric indicator in EDTA titration of calcium ions and fluorescence assays. Additionally, Calcein calcium potassium can be used as a model drug to assess the efficiency and bioavailability of drug delivery systems.

Calcein Blue AM is a live cell labeling dye that permeates the cell membrane. Upon entering cells, intracellular esterases cleave the ester group of acetoxymethyl (AM), producing Calcein Blue fluorescent dye that is impermeable to cell membranes.

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 is a fluorogenic dye that is used to assess cell viability. As the acetoxymethyl ester, Calcein Red AM is non-fluorescent but cell-permeant and is hydrolyzed to the fluorescent probe Calcein Red by intracellular esterases. Calcein Red is retained by living cells and displays excitation emission maxima of 560 574 nm, respectively. Calcein Red AM is a red-emitting variant of the green fluorophore calcein AM , which has been used to evaluate cell viability and cytotoxicity.

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.
