describe a real life application of the plaque assay

Expert Solution

The plaque assay is a very well-established tool for evaluating concentration of viruses as it relates to the dose of infection. This assay is focused on calculating the number of pfu (plaque-forming units) produced within a virus-infected cell monolayer. Once a virus-infected cell lysis, plaques form, leading to a subsequent process of neighboring cell infection and lysis. PRNT (Plaque Reduction Neutralization) assay is a powerful twist on the plaque assay used to test antibody nutrilizarion.

Plaque-based assays are the typical approach used to assess infectious dose concentration of the virus.

Utility of plaque assay is to phenotypic characterization of a genetically modified Plasmodium falciparum clone known to exhibit a poorly defined growth defect.

Plaque assay also used by testing separate plaques in cell culture for the direct quantification of infectious antiviral substances and virons.

You are counting plaques on your plaque assay plates made from serial dilutions of your high titer lysate. Your 10-5 plate has 615 plaques although some are butting up against each other so it is difficult to get an accurate count. Your 10-6 plate has 42 plaques, and your 10-7 plate has only 1 plaque. Which plate would probably yield the most accurate titer calculation of your phage and why is it more trustworthy than the others?

These quistion related to Oxidase Assay for Respiration and Catalase Assay experiment 1.In the clinical (real-world) setting, what is the main objective of performing laboratory tests such as the oxidase or catalase assays? 2.Some very important pathogens are positive for the oxidase test. Use your text or the Internet to find one such example. 3.A student performing the Experiment 2 of this lab set up a positive control with a known catalase-positive bacterium. However, he had no remaining hydrogen peroxide...
