Test très sensible pour la mesure de l'attachement arénavirus-cell

Overview

This protocol outlines a quantitative method for measuring arenavirus particle attachment to host cells using a highly sensitive qRT-PCR-based assay. The technique can also be adapted to study virion endocytosis and genome release into the cytoplasm.

Key Study Components

Area of Science

• Virology
