ELISA Products

An ELISA (enzyme-linked immunosorbent assay) is a plate-based assay for detecting and quantifying soluble molecules such as antibodies, proteins, peptides, haptens and drugs.

In an ELISA, the antigen (molecule to be detected and quantified) is immobilized onto a solid surface (microplate) and then complexed with an antibody that is conjugated to a reporter enzyme (e.g., Horseradish Peroxidase). These complexes are then incubated with the appropriate substrate for the reporter enzyme to produce a measurable product. The most essential element of any ELISA is a highly specific antibody-antigen interaction.



ELISA Applications


  1. Medical Diagnostics Detection of infectious diseases and autoimmune disorders by identifying specific antibodies or antigens in samples.
  2. Food Industry: Ensures food safety by testing for allergens and pathogens, like peanuts and E. coli, in food products.
  3. Environmental Monitoring: Screens for environmental contaminants in water and air, including pesticides and allergens.
  4. Research and Development: Biological research by measuring hormone levels and investigating protein interactions in disease studies.
  5. Veterinary Diagnostics:  Diagnosing animal diseases and managing breeding by testing for specific diseases and hormone levels.
