(AI) AVIAN INLUENZA ANTIBODY Test Kit
The AI ELISA kit will measure the amount of antibody to AI in the serum of chickens and Turkeys. Microtitre plates have been pre-coated with inactivated AI antigen. Serum samples are diluted and added to the microtitre wells where any anti-AI antibodies present will bind and form an antigen-antibody complex. Non-specific antibodies and other serum proteins are then washed away. Anti-chicken IgG labelled with the enzyme alkaline phosphatase is then added to the wells and binds to any chicken anti-AI antibodies originally bound to the antigen. After another wash to remove unreacted conjugate, substrate is added in the form of pNPP chromogen. A yellow colour is developed if anti-AI antibody is present and the intensity is directly related to the amount of anti-AI present in the sample.
