Cell Proliferation Assay based on Cellular DNA Content

Introduction

Our Cell-Quant™ No Wash Cell Proliferation Assay Kit (A014) provide an accurate microplate–based fluorescence method for counting cells in a population, based on cellular DNA content. Our Cell-Quant™ Assay provide a very convenient workflow for high-throughput screening of cell proliferation and cytotoxicity–no washes, cell lysis, temperature equilibrations, or radioactivity required (Figure 1). The Cell-Quant™ Assay has a linear detection range from less than 100 to 20,000 cells per well in most cell types (Figure 2). The add-mix-read assay format makes it ideal for HTS applications. The assay can be completed in one hour, and the signal is stable for several hours, affording additional work flow convenience.

Figure 2. Quantitation of CHO cells using the Cell-Quant™ No Wash Cell Proliferation Assay Kit. Fluorescence measurements were made using a microplate reader with excitation at 485 nm and emission detection at 530 nm. The linear range of the assay under these conditions is from 100 to 20,000 cells per 100 µl sample. The inset shows the linearity that can be obtained at very low numbers of cells.
