Biotium Fluo-3, AM Ester, Special Packag, 20x50ug
Membrane-permeant AM ester form of Fluo-3 that can be loaded into cells via incubation. Because of the relatively low water solubility of the AM ester, Pluronic F-127, a mild detergent, is often used as a dispersing agent to facilitate dye loading. Fluo-3 AM ester itself does not bind Ca2 , but it is readily hydrolyzed to Fluo-3 by endogenous esterases once the dye is inside the cells. An important application of Fluo-3 AM ester is its use in high throughput drug screening. Properties: Orange red solid soluble in DMSO; Store -20°C and protect from light, especially when in solution; C51H50Cl2N2O23; MW: 1129.9; [121714-22-5]
Biotium Fura-2, AM Ester, 20x50ug
Fura-2, AM ester is an intracellular fluorescent calcium indicator, and the preferred dye for ratiometric imaging microscopy. The membrane-permeant AM ester can be loaded into cells via incubation, but due to limited water solubility, a mild detergent Pluronic F-127 is often used to facilitate cell loading. Fura-2, AM ester itself does not bind Ca2, but intracellular esterases readily hydrolyze it to Fura-2. Upon calcium binding, the excitation maximum of Fura-2 undergoes a blue-shift from 363 nm (no Ca2) to 335 nm (high Ca2) while the emission maximum is relatively unchanged. Measure by flow cytometry, fluorescence microscopy, or certain fluoresence microplate readers. Properties: Light yellow solid soluble in DMSO; Store at -20°C, protect from light, especially in solution; Kd: 145 nM (22°C, pH 7.2 buffer); Ex/Em = 363/512 nm, e = 27,000 M-1cm-1 (no Ca2); Ex/Em 335/505 nm, e = 35,000 M-1cm-1 (high Ca2); C44H47N3O24; MW: 1001.9; [108964-32-5].
Biotium Furaptra, AM Ester, 20x50ug
Furaptra, AM ester is a membrane-permeant form of Furaptra (Mag-Fura-2). The indicator is loaded into cells via simple incubation, where it is cleaved by cytoplasmic esterases to release Mag-Fura-2. Properties: Light yellow solid soluble in DMSO; Store at -20°C and protect from light; C30H30N2O19; MW: 723
