People Also Ask about

What is an NAI assay?

Phenotyping: neuraminidase inhibition assays Two types of neuraminidase (NA) inhibition assays are commonly used for determining influenza susceptibility to the NA inhibitor (NAI) antivirals: fluorescence-based (FL) and chemiluminescence-based (CL) assays.

How does enzyme-linked fluorescent assay work?

This secondary antibody is chemically linked in advance to an enzyme. Thus, the plate will contain enzyme in proportion to the amount of secondary antibody bound to the plate. A substrate for the enzyme is applied, and catalysis by the enzyme leads to a change in color or fluorescence.

What is the principle of enzyme-linked immunosorbent assay?

Enzyme-linked immunosorbent assay (ELISA) is a method of target antigen (or antibody) capture in samples using a specific antibody (or antigen), and of target molecule detection/quantitation using an enzyme reaction with its substrate.

What is the specific diagnostic test for influenza?

Diagnostic tests available for detection of influenza viruses in respiratory specimens include molecular assays (including rapid molecular assays, reverse transcription polymerase chain reaction (RT-PCR) and other nucleic acid amplification tests); and antigen detection tests (including rapid influenza diagnostic tests

What is the screening tool for influenza?

The IRAT is used for evaluation of flu viruses Together these scores indicate the likelihood that a virus will gain the ability to spread from person-to-person and the potential public health impact if that were to happen.

How does an enzyme-linked immunoassay work?

ELISA assays are usually chromogenic using a reaction that converts the substrate (e.g. TMB or ABTS) into a coloured product which can be measured using a plate reader. Determination of antigen concentration in a sample requires production of a standard curve using antigens of a known concentration (shown in Figure 2).

What is a NAI assay for influenza?

Phenotyping: neuraminidase inhibition assays Two types of neuraminidase (NA) inhibition assays are commonly used for determining influenza susceptibility to the NA inhibitor (NAI) antivirals: fluorescence-based (FL) and chemiluminescence-based (CL) assays.

What is the gold standard diagnostic test for influenza diagnosis?

The gold standard for confirming influenza virus infection is reverse transcription-polymerase chain reaction (RT-PCR) or viral culture of nasopharyngeal or throat secretions.

How does an enzyme-linked lectin assay work?

The assay is based on the ability of NA to cleave SA residues from a substrate, usually fetuin coated on the surface of 96-well plates. Removal of SA exposes a galactose residue, which is bound by a lectin [peanut agglutinin (PNA)] conjugated to horseradish peroxidase (HRP).
