Virus replication is a complex and highly coordinated process. After entering a cell, a virus undergoes several processes to multiply in order to produce more progeny viruses. Although the replication process varies greatly between virus types, all viral replication cycles involve the following steps: I) attachment to and entry into the host cell, followed by shedding of the capsid structure and release of the viral genome; II) replication of the genome and synthesis of viral particle components in the host cell; III) assembly and release of the offspring virus from the host cell. Real-time monitoring of viral replication is important for the suppression of virus transmission and the treatment of viral diseases. Therefore, imaging analysis of the viral replication process is a key concern for researchers.

Viral Replication Imaging Analysis

In recent years, the study of viral replication has shifted from overall measurements to imaging analysis at the single-particle level. Traditional fluorescence microscopy techniques allow researchers to observe the details of viral and individual replication at a point in time to obtain detailed quantitative information. However, traditional imaging techniques can only provide a snapshot of virus replication, they cannot monitor the entire process of virus replication in real time.

CD BioSciences has been committed to the development of fluorescent dyes and imaging technology for many years. We can use VIRIM technology to monitor the replication of individual viruses in host cells in real time to study the heterogeneity of replication dynamics between cells.
