Used in biomedical research to detect and quantify neuraminidase activity in human samples. Helps in studying viral infections, particularly influenza, where neuraminidase plays a key role in viral release and spread. Enables researchers to evaluate immune responses, assess antiviral drug efficacy, and support vaccine development. Commonly applied in clinical labs and virology studies for accurate measurement of neuraminidase levels in cell cultures, serum, and other biological fluids.
