Single-Virus Imaging Tracking Services

Viruses are a variety of pathogens whose main task is to infect host cells and reproduce within them to produce offspring viruses. Virus infection of host cells is a complex process and can cause viral diseases. The outbreak of viral diseases not only poses a major threat to human health, but also causes huge losses to social economy. Therefore, imaging studies of the mechanisms of viral infection of cells are critical for preventing the spread and treatment of viral diseases.

Single-Virus Imaging Tracking

Early researchers used biochemical experiments and transmission electron microscopy to study the mechanisms by which viruses infect host cells. However, transmission electron microscopy can only acquire static images when studying the viral infection pathway. In vitro biochemical experiments require overall measurements of samples isolated from organisms and then inferring the effects. While conventional methods cannot obtain dynamic information about individual viruses during the infection process, single virus tracking technology, allows researchers to directly observe the infection process in living cells, thus revealing the mechanisms of virus infection and proliferation.

CD BioSciences is a biotechnology company, which has been committed to the development of fluorescent dyes and imaging technology for many years. We can use single virus tracking techniques to directly observe virus dynamics in living cells to reveal the multiple complex infection mechanisms of various viruses. SVT is based on fluorescence imaging and is a valuable tool in virological research.
