Viral Particle Structure Imaging Services

Viruses are a variety of pathogens ranging from ten to several hundred nanometers in diameter. Most viruses are mainly composed of nucleic acids (RNA or DNA), structural proteins and lipid membranes. The protein coat of a virus can change and assemble to initiate viral infection and replication. Therefore, it is important to image and analyze the structure of viruses to obtain information about their size, morphology, composition and internal protein distribution.

Viral Particle Structure Imaging Analysis

Fluorescence microscopy provides an easy imaging method for virus imaging. However, viruses are relatively small, with individual virus particles typically less than 220 nanometers in diameter. Due to the diffraction limit, optical microscopy cannot accurately visualize the structure of viruses. Fluorescence super-resolution microscopy bypasses the diffraction limit and becomes a novel tool for virus imaging.

CD BioSciences has been committed to the development of fluorescent dyes and imaging technology for many years. We can image thousands of individual virus particles through fluorescence super-resolution microscopy and rapid automated analysis platforms, and we can provide you with information on viral particle size, morphology, and its composition.
