Employs specific antibody-antigen reactions in agar gel to detect the presence of horse meat and the percentage of that adulteration in fresh ground beef. Indicators for the meats are their unique blood serum albumins (the antigens). Double immunodiffusion and single radial immunodiffusion in agar gel are the qualitative and quantitative tests, respectively, conducted in the exercise. Supplies are sufficient for 4 “hands-on” participants. (Some reagents are shared; hot-water bath is required.) Also an excellent demonstration in conjunction with our item# 202100 Immunodetective BioKit®. Contains perishable items; please give use date on order.
