During this time, many normal functions normally performed on our website, such as placing an order or paying an invoice, will not be available. We apologize for the inconvenience but will have complete return of services on Monday, December 16th.

Cell Proliferation Assay Kits

ATCC Cell Proliferation Assay kits are convenient and valuable tools for the quantitative evaluation of a cell population's response to external factors that affect cell viability and growth.

MTT Cell Proliferation Assay Kit

Offers a quantitative, convenient method for evaluating a cell population's response to external factors, whether it be an increase in cell growth, no effect, or a decrease in growth due to necrosis or apoptosis.

Reliablue Reagent

Is a resazurin-based cell proliferation assay that is sensitive and non-toxic. This single-component reagent can determine cell viability and proliferative capacity of live adherent and suspension cell cultures. The assay is quantitative, sensitive, scalable, and has continuous, non-endpoint capabilities.  


XTT Cell Proliferation Assay Kit

Utilizes the second generation tetrazolium dye, XTT (sodium 2,3,-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)-carbonyl]-2H-tetrazolium inner salt), to measure cell growth, cytotoxicity, and apoptosis. It is a homogenous, highly sensitive, reproducible assay, and adaptable to high-throughput screening.
