Virology is the study of viruses. It focuses on these aspects of viruses: their structure, classification and evolution, their ways to infect and exploit host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. Virology is considered to be a sub-discipline of microbiology. Learn more about this field of biology here.
A crude lysate gel assay can be performed to roughly quantitate the DNA in lysates. This is often a valuable time saving step to determine if the phage yield is sufficient to warrant continuing the procedure.
Spotter is a program designed to measure the sizes of viral plaques. The surface area contained within the perimeter of the plaque can be calculated either in millimeters squared or in arbitrary units (pixels).
