Cell proliferation analyses are crucial for cell growth and differentiation studies, and are often used to evaluate both compound toxicity and inhibition of tumor cell growth during drug development. Proliferation measurements in microplate assays are typically based on average DNA content or cellular metabolism, or they quantify DNA synthesis.
CyQUANT cell proliferation assays provide an accurate microplate-based fluorescence method for counting cells in a population, based on cellular DNA content. Because cellular DNA content is highly regulated, the CyQUANT assay can be used at multiple time points to calculate the average proliferation rate of a cell population. Binding of the CyQUANT dye to DNA is independent of metabolic state, so signal windows and fluorescence intensities can be compared across a range of conditions and cell types.
A variety of CyQUANT assay formats provide options for different workflows, including multi-day and endpoint assays for total cell numbers and assays for live cells.
Measuring the synthesis of new DNA is a precise way to assay cell proliferation in individual cells or in cell populations. The Click-iT EdU assay measures the rate of new DNA synthesis based on incorporation of the nucleoside analog EdU into the newly synthesized DNA in live cells. Detection is achieved through a copper-catalyzed “click” reaction that is typically completed within 30 minutes.
The Click-iT Plus EdU Microplate Assay is optimized for microplate fluorescence analysis:
