Quantitation of virus using laser-based scanning of near-infrared fluorophores replaces manual plate reading in a virus titration assay

A method was developed for quantitation of a virus titration assay for minimally cytopathic and noncytopathic viruses that utilizes laser-based scanning of near-infrared (NIR) fluorophores. This automated method bypasses the need for manual plate reading thus eliminating human bias and error. The image data is translated by LI-COR's Odyssey software into numerical data which is used directly in the virus titer calculations.
