Product details:
Neuraminidase Assay Kit (Fluorometric - Blue) (ab138888) provides a sensitive and robust fluorometric assay to detect neuraminidase that exists either in cells or biological samples. The non-fluorescent neuraminidase substrate becomes strongly fluorescent upon neuraminidase cleavage. The kit can detect as little as 0.3 mU/mL neuraminidase in a 100 uL assay volume. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation without a separation step. The signal can be easily read by a fluorescence microplate reader at Ex/Em = ~320/~450 nm.
Other Notes
Neuraminidases, also called sialidases, are glycoside hydrolase enzymes that catalyze the hydrolysis of terminal sialic acid residues and neuraminic acids. The most commonly known neuraminidase is the viral neuraminidase. The cleavage of linkage between sialic acid and adjacent sugar residue permits the transport of the virus through mucin and destroys the haemagglutinin receptor on the host cell, thus allowing elution of progeny virus particles from infected cells. Neuraminidase promotes influenza virus release from infected cells and facilitates virus spread within the respiratory tract. Thus, it is an important target for influenza drug development. The detection of neuraminidase and screening its inhibitors is one of the essential tasks for investigating biological processes and prevention of influenza infection.

Neuraminidase sometimes called sialidase functions as an enzyme that cleaves sialic acid residues from glycoproteins and glycolipids. This process is essential for the maturation and release of progeny viruses from infected cells. Enzymatically active neuraminidase proteins weigh about 60 kilodaltons and localize on the surface of influenza viruses. Researchers identify its expression on the viral envelope playing a pivotal role in the viral life cycle. Neuraminidase activity is an important target for drug development against influenza.
Biological function summary
Neuraminidase significantly impacts viral virulence and host cell infection. It is part of the functional machinery required for viral particle detachment from the host cell membrane facilitating the spread of infection. Neuraminidase works alongside other viral proteins including hemagglutinin which attaches the virus to the host cell. The neuraminidase function of trimming sialic acids is critical in the ongoing interaction between virus and host.
Pathways
The influenza lifecycle heavily involves neuraminidase-mediated sialic acid cleavage. This enzyme contributes to pathways by enabling the efficient release of new viral particles enhancing the infectivity of the virus. Neuraminidase operates in concert with hemagglutinin which initially binds the virus to host cells by attaching to the sialic acid residues. This interplay is vital in viral replication pathways which propagate the infection cycle.
Influenza directly relates to neuraminidase as it is a primary means by which the virus spreads within the host. Neuraminidase inhibitors are a class of antiviral drugs that target this protein important for treating and managing influenza infections. Besides influenza research links neuraminidase activity to bacterial infections with some bacterial neuraminidases implicated in the pathogenesis of diseases like pneumonia. The relationship to hemagglutinin in viral influenza highlights the significance of neuraminidase as a target in therapeutic interventions.
