Proteon Egg Express


In 10 minutes and without equipment, anyone can verify that your production does not contain egg.

Are you considering of doing allergen control but you do not know how to approach it?
Do you want to verify cleaning between productions when sharing production lines?
Do you have many products to analyse and you need results immediately or within a day?
Are you implementing an IFS, BRC, ISO 22000 2005 quality standard?
Do you work with powdered egg and you could have contaminations after cleaning?


The speed and simplicity of the Proteon Express tests allow adapting the allergen analysis to the time and place you need. Having specific information will allow us to make immediate decisions between productions, detect insufficient cleanings, control critical points of contamination and ensure the release of your product to the market without risk.


Immunochromatographic assay, in a fast strip format, based on the detection of ovalbumin by a specific antibody in a non-competitive sandwich assay.


  • Limit of detection: 0.5 ppm of egg protein.
  • Limit of detection in surfaces: 0.25 µg of protein.
  • Assay time: 10 min.
