ProtoCheck is an innovative test patented by prof. Celotti of University of Udine; it’s based on the reaction between the proteins present in a potentially unstable liquid (wine or beverage with acidic pH), with a mixture of stabilized anionic compounds.
Advantages:

• The sample doesn’t have to be filtered
  Rapidity (60 seconds) and specificity of the reaction with the potentially unstable proteins
  No significant interference in the method of analysis
  Standardized method of analysis for comparable results between different laboratories.
