Overview
Today’s research and biologic production demands on cell and tissue culture
assumes no guesswork to confirming viable cell populations. Therefore, both cell
concentration and percentage of viable cells must be determined accurately and
precisely. The new Vi-CELL Series Cell Viability Analyzers provide an automatic
and cost effective means to perform the trypan blue dye exclusion method. This
data is essential to the decision making process for basic tissue culture cell
passage and maintaining optimum culture conditions in bioreactors. Cell and
tissue culture applications in life science research, including recombinant
protein and biopharmaceutical production, require the accuracy, precision and
automation available only in the Vi-CELL cell viability analyzer.
The Vi-CELL automates the widely accepted trypan blue cell exclusion method.
Historically, cell viability determinations were performed manually using a
light microscope and hemacytometer. This technique has major shortcomings due to
subjective determination of cell count, as well as manual, time consuming steps.
In comparison to the manual technique, the Vi-CELL automatically performs the
trypan blue with video imaging of the flow-through cell. Results are obtained in
minutes.
