Sample Type: Plant tissues Intended Use: For the quantitative determination of endogenic plant hormone abscisic acid (ABA) concentrations in plant tissues. Sensitivity: 0.04ug/ml Range: 0.156-10ug/ml Specificity: Cross reaction rate: Abscisic acid: 100%, Gibberellin: <0.01%, Indoleacetic acid: <0.01% Test Principle: This BioAssay? employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with antigen. Standards or samples are added to the appropriate microtiter plate wells with an antibody specific for ABA. The competitive inhibition reaction is launched between with pre-coated ABA and ABA in samples with the antibody. Then add a Horseradish Peroxidase (HRP) conjugated goat-anti-rabbit IgG antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of ABA in the sample. The color development is stopped and the intensity of the color is measured.
