Influenza B Virus Antibody (FluB) (IgA) BioAssay™ ELISA Kit (Human)

Sample Type:
Serum

Intended Use:
For the qualitative determination of human influenza B virus (FluB) antibody (IgA) concentrations in serum.

Specificity:
This assay has high sensitivity and excellent specificity for detection of human influenza B virus (FluB) antibody(IgA). No significant cross-reactivity or interference between human influenza B virus (FluB) antibody(IgA) and analogues was observed.

Test Principle:
This BioAssay™ employs the qualitative enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with antigen. Samples are pipetted into the wells with anti-human IgA conjugated Horseradish Peroxidase (HRP). Any antibodies specific for the antigen present will bind to the pre-coated antigen. Following a wash to remove any unbound reagent, a substrate solution is added to the wells and color develops in proportion to the amount of human influenza B virus (FluB) antibody(IgA) bound in the initial step. The color development is stopped and the intensity of the color is measured.
