Biotium Calcofluor White Stain, 5 mM in Water. 20ml

Calcofluor White is a fluorescent blue dye that binds to cellulose and chitin, which can be found in the cell walls of fungi, algae, and plants. In budding yeast Calcofluor White stains bud scars more strongly, because they have a higher concentration of chitin. Calcofluor White is sometimes used to identify fungal infections in medical samples. Calcofluor White also stains gram-positive bacteria, but not gram-negative bacteria or mammalian cells. Properties: Provided as a 5 mM solution in water; Ex/Em 360/430 nm; Store at -20¿C, protected from light; C40H44N12O10S2; MW: 916.98

Biotium Calcein AM

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
