Biotium Calcein AM, 4 mM in Anhydrous DMSO
Calcein AM is a widely used green fluorescent cell marker. Calcein AM is membrane-permeant and thus can be introduced into cells via incubation. Once inside the cells, calcein AM is hydrolyzed by endogenous esterase into the highly negatively charged green fluorescent calcein, which is retained in the cytoplasm. Calcein AM is an excellent tool for the studies of cell membrane integrity and for cell tracing. Supplied in lyophilized form or as a solution in anhydrous DMSO at 4 mM (80011-1) or 1 mg/mL (1 mM) (80011-2). Calcein AM is also offered in our Cell Viability and Cytotoxicity Assay Kit. Properties: Ex/Em (calcein) = 494/517 nm (pH 8); Colorless solid soluble in DMSO; Store at -20°C and protect from light; C46H46N2O23; MW: 995
Biotium Rhodamine 123
Rhodamine 123 is a popular green fluorescent mitochondrial dye that stains mitochondria in living cells in a membrane potential-dependent fashion. It is widely used in flow cytometry studies involving mitochondrial membrane potential. Please also see Dihydrorhodamine 123 and its HCl salt.Properties: Ex/Em(MeOH) = 505/534 nm; e (505 nm, MeOH) = 97,000; Orange red solid soluble in DMSO or DMF; Store at 4°C and protect from light, especially in solution; C21H17ClN2O3; MW: 381; [62669-70-9]
Biotium APTS (8-AMINOPYRENE-1,3,6-TRISULFONIC ACID, TRISODIUM SALT)
APTS is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general. The labeling occurs via reductive amination which involves the formation of a Schiff base between the amine of APTS and the aldehyde or ketone of the sugar, followed by the reduction of the Schiff base linkage to a stable carbon-nitrogen bond. The multi-anionic nature of the dye makes it ideal for the studies of carbohydrate molecules by high resolution capillary electrophoresis. &lamba; Ex/&lamba; Em: 424/505 nm (before conjugation) Yellow solid soluble in water Store at 4°C and protect from light. C16H8Na3O9S3 MW: 523.39 [196504-57-1]
