Cell Viability Assay Kit
Cell Meter™ Cell Viability Assay Kit *NIR Fluorescence Optimized for Fluorescence Microplate Reader*
This kit uses a proprietary dye that gets enhanced fluorescence upon entering into live cells. The dye is a hydrophobic compound that easily permeates intact live cells. The hydrolysis of the weakly fluorescent substrate by intracellular esterases generates a strongly fluorescent hydrophilic product that is well-retained in the cell cytoplasm. The esterase activity is proportional to the number of viable cells, and thus directly related to the fluorescence intensity of the product generated from the esterase-catalyzed hydrolysis of the fluorogenic substrate. Cells grown in black-walled plates can be stained and quantified in less than two hours. The assay is more robust than the tetrazolium salt or Alarmar Blue?based assays. It can be readily adapted for high-throughput assays in a wide variety of fluorescence platforms such as microplate assays, immunocytochemistry and flow cytometry. ?t is useful for a variety of studies, including cell adhesion, chemotaxis, multidrug resistance, cell viability, apoptosis and cytotoxicity. The kit provides all the essential components with an optimized cell-labeling protocol. It is suitable for proliferating and non-proliferating cells, and can be used for both suspension and adherent cells. Using 100 ul of reagents per well in a 96-well format, this kit provides sufficient reagents to perform 200 assays. Using 25 ul of reagents per well in a 384-well format, this kit provides sufficient reagents to perform 800 assays.
Key Features

Rapid Dye Loading : Dye loading at RT for 30 min to 1 hr.
Convenient and Robust : Formulated to have minimal hands-on time.
Versatile applications : Compatible with many cell lines and targets
Kit Components
Component A : CytoCalcein™ NIR 2 vials, lyophilized
Component B : DMSO 1 vial (100 μL)
Component C : Assay Buffer 2 bottle (10 mL/bottle)
Brief Summary
→ Prepare cells with test compounds
→ Add the same volume of dye-loading solution (100 μL for 96-well plate or 25 μL for 384-well plate)
→ Incubate at room temperature or 37℃ for 1 hr
→ Read Fluorescence at Ex/Em = 635/670 nm
