Product Description
CellQuanti-Blue Cell Viability Assay Kits 5000 Tests
Application: Homogeneous assay for cell viability, proliferation, cytotoxcity and high-throughput screen for anticancer agents.
Key Features:
- Safe. 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 factors of 0.6 to 0.9 are routinely observed in 96-well and 384-well plates. Can be readily automated on HTS liquid handling systems.
Method: FL530/590nm

More Details:
This homogeneous assay involves simply adding a single reagent, the CellQuanti-Blue™ reagent, to the cell culture and measuring the fluorescence intensity (excitation wavelength = 530 - 570 nm, emission wavelength = 590 - 620 nm) after an incubation step. The CellQuanti-Blue™ reagent, like other 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.
The CellQuanti-Blue™ 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.
