Isolation and Genome Analysis of Single Virions using ‘Single Virus Genomics’

Overview

Single Virus Genomics (SVG) is a method designed to isolate and amplify the genomes of single virons from mixed viral suspensions. This technique employs flow cytometry for sorting and utilizes multiple displacement amplification (MDA) for whole genome amplification, facilitating subsequent sequencing.
