Pullorum Disease (PD) and Fowl Typhoid (FT) Antibody ELISA Kit

Principle

The Pullorum Disease (PD) and Fowl Typhoid (FT) antibody ELISA kit is based on an indirect enzymatic immunoassay (Indirect ELISA). The antigen is coated on plates. When a sample serum contains specific antibodies against virus, they will bind to the antigen on plates. Wash the unbound antibodies and other components. Then add a specific enzyme conjugate. After incubation and washing, add the TMB substrate. A colorimetric reaction will appear, measured by a spectrophotometer (450 nm).
