Intended Use

Enzyme immunoassay for the qualitative detection of Bovine ASV antigen in serum, plasma, culture media, or any biological fluid.

Principle

The qualitative detection of Bovine ASV antigen is based on the Double Antibody Sandwich ELISA (Enzyme-Linked Immunosorbent Assay) technique. The microplate wells are pre-coated with Bovine ASV-specific antibodies. The corresponding antigen in the sample binds the immobilized antibodies after incubation. After washing the microplate wells to remove all unbound sample material, horseradish peroxidase (HRP) labeled antibody conjugate specific for Bovine ASV Antigen is added, which binds the captured antigen, forming antibody-antigen enzyme-labeled antibody complex upon incubation. In a second wash step, the unbound conjugate is removed. The immune complex formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue color reaction in wells containing the complex. A stop solution containing acid terminates the reaction, producing a yellow end-point coloration proportional to the amount of target antigen present in the sample. Absorbance is measured at 450 nm using an ELISA microwell plate reader. Analysis is completed by comparing the OD values of samples to a cut-off value.
