Plaque assays are laboratory techniques used to quantify the number of viable virus particles in a sample by measuring their ability to infect host cells. In this method, a diluted viral sample is added to a layer of susceptible cells, and after incubation, the formation of clear zones or "plaques" indicates areas where the virus has successfully infected and killed the cells. This provides a visual representation of viral infectivity and allows researchers to calculate the viral titer. Plaque assays are commonly used in virology for studying virus characteristics, assessing antiviral drug efficacy, and evaluating viral pathogenesis.

What is molecular assays?
Molecular assays are laboratory techniques that detect and analyze the genetic material (DNA or RNA) of organisms. These assays are used to identify specific genes, mutations, or pathogens, and are widely used in research, diagnostics, and pharmaceutical development. Examples of molecular assays include polymerase chain reaction (PCR), next-generation sequencing (NGS), and hybridization assays.

What is the significance of NADH absorbance in biochemical assays?
NADH absorbance is significant in biochemical assays because it can be used to measure the activity of enzymes involved in cellular respiration. Changes in NADH absorbance indicate the conversion of NADH to NAD by enzymes, providing valuable information about metabolic processes and enzyme function.
