Sigma Aldrich Fine Chemicals Biosciences Live Dead Cell Viability A

The Live-Dead Cell Viability Assay Kit is a quick and simple three-color assay to measure cell viability. The kit consists of Calcein-AM (stains live cells) Propidium Iodide (stains dead cells) and Hoechst 33342 (stains all cells). The kit has been optimized for 3D cell culture (spheroids human organoids and 3D matrices) and 2D cell culture (multiple cell types). The kit can be used for flow cytometry fluorescence microscopy and with fluorescence microplate readers. The kit determines viability of cells based on plasma membrane integrity and esterase activity. One kit contains reagents sufficient for 5 x 24-well plates or 12 x 96-well plates.boldAdvantages/bold 1. Tested and optimized for 3D cell culture Spheroid culture organoid culture 2D cell culture and flow cytometry.2. Easy to use and quick protocol.3. Stronger intensity of Calcein AM and Hoechst dyes compared to other products.Spectral PropertiesCalcein AM Ex/Em 490/515 nm (Green)Propidium Iodide Ex/Em 535/617 nm (Red)

Biotium Fura-2, AM Ester, 1mM In Anhydrous DMSO

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, Tetrasodium Salt

Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a Kd of 1.9 mM. Similar to Fura-2, the excitation wavelength of Mag-Fura-2 undergoes a blue shift from 369 nm to 330 nm. Mag-Fura-2 also responds to Ca2 but with a significantly lower Kd than Fura-2 for Ca2 . An important application of Mag-Fura-2 is its use in detecting high, transient Ca2 concentration during Ca2 spikes. Mag-Fura-2/tetrasodium salt can be loaded into cells by microinjection or scrape loading. Also available are Mag-Fura-2, tetrapotassium salt and the cell membrane-permeant Mag-Fura-2 AM ester. Properties: Light yellow solid soluble in water (pH > 6); Store at 4°C and protect from light C18H10N2Na4O11; MW: 523
