| 摘要 |
The invention discloses a simple, accurate and reproducible method of determining viral particle concentration, especially for any serotype of adenovirus. More specifically, an accurate absorptivity/extinction coefficie nt in units of viral particles per milliliter per absorbance unit per centimete r (vp/mL-AU-cm) for a sample virus, such as adenovirus, at 260 nanometers (nm) is disclosed, as well as an ultraviolet (UV) absorbance method to determine virus particle concentrations based on this established absorptivity/extinction coefficient and absorbances at 260 nm for purified virus preparations, such as adenovirus preparations.
