Cell Viability Assay Kit, BioAssay(TM), High Sensitivity

This homogeneous assay involves simply adding a single reagent to the cell culture and measuring the fluorescence intensity (excitation wavelength=530-570nm, emission wavelength=590-620nm) after an incubation step. The resazurin-based assays such as the Alamar Blue reagent, utilizes the redox dye resazurin which is not fluorescent, but upon reduction by metabolically active cells is converted into a highly fluorescent product (resorufin). Living cells can readily reduce this non-toxic reagent and the resulting increase in fluorescence intensity can be conveniently monitored using a fluorescence spectrophotometer or plate reader. Nonviable cells have no metabolic capacity and, thus, will not reduce the dye. Therefore, the fluorescence intensity observed in this assay is a true measure of the viable cells.\n\nThe reagent has been optimized for maximum sensitivity, reproducibility and long shelf-life. The homogeneous cell-based assay can be performed in multi-well plates. The reagent is compatible with all culture media and with all liquid handling systems for high-throughput screening applications in 96-well and 384-well plates. applications include cell proliferation, cytotoxicity and apoptosis.\n\nKey Features:\nSafe. Non-radioactive assay (cf. 3H-thymidine incorporation assay). Sensitive and accurate. As low as 100 cells can be accurately quantified. Time efficient. High-throughput assay in 96-well and 384-well plates allows simultaneous processing ten of thousands of samples per day. Homogeneous and convenient. A single reagent and "mix-incubate-measure" type assay. No wash and reagent transfer steps are involved. Robust and amenable to HTS: Z
