Ag Detection

A slide agglutination test is also used for the direct qualitative detection of antigen in biological fluids, food and water.

In this application, Estapor® microspheres are coated with monoclonal or polyclonal antibodies and when mixed with samples containing the corresponding antigen a positive agglutination occurs.

Estapor® microspheres are also used worldwide as the inert support in antigen Latex Agglutination Tests (LAT):

  • Clinical Diagnostics
    • Infectious disease: HBsA
    • Pregnancy test: beta-hCG

  • Food Industry
    For food industries, food borne pathogen testing is a major concern for the following agents: E. ColiO157, Listeria SPP, Listeria monocytogen, Salmonella, Campylobacter, Vibrio.

  • Environment Sampling
    Microbiological analysis of environmental sampling is becoming more and more frequent for safety reasons: L. pneumophila and L. non-pneumophila species, Amibia, Cryptosporidium.

  • Veterinary Diagnostics
    For veterinary diagnostics, infectious diseases and pathogen testing are also major concerns for safety reasons: HBsAg, Leptospirosis, Malaria, and Dengue.
