With the exception of plants, almost all living organisms synthesize
neuraminidase/
sialidase. It is a one among the crucial
proteins that controls how virulent a microorganism is. An essential
enzyme in orthomyxoviruses and paramyxoviruses that destroys receptors is
neuraminidase. It plays a number of roles throughout the viral life cycle in addition to one that involves the release of progeny virus particles. This
protein is an important target for therapeutic interventions and diagnostic assays.
Neuraminidase inhibitors effectively prevent the spread of disease and
viral infection. Sensitive, quick, and inexpensive high throughput assays are needed to screen for specific
neuraminidase inhibitory chemicals. To characterize the
neuraminidase catalytic activity, however, the traditional assays are still the most common in laboratories. This review gives a brief overview of these
neuraminidase assays and recent, innovative developments, particularly those involving biosensors.
