Introduction of new allergens at CACLP 2019

This year’s CACLP 2019 gave us the opportunity to meet customers and partners from China and all over the world to catch up on business and to discuss different expectations. We are sure that innovation through collaboration is the essential key for the development of high quality IVDs.

We appreciate your interest in our latest product innovations. DIARECT is dedicated to permanently improve more high quality products. We are proud to introduce our new food allergens

  • non recombinant Cor a 9 
  • recombinant Tri a 14.0101


Hazelnut (Corylus avellana) belongs to one of the most potent elicitors of food allergy. Patients sensitized to the hexameric non-glycosylated storage protein and minor allergen, Cor a 9, are likely to react to raw and roasted hazelnut. The 11S legumin-like seed storage globulin, also known as corylin, is associated with severe systemic reactions.

The family of 11 S-globulins represents precursor proteins which are cleaved into two chains, originally linked together by a disulphide bond. The true food storage protein or pollen-independent hazelnut allergen indicates a primary hazelnut allergy as it does not show cross-reactivity to Bet v 1 as for e.g. Cor a 1.

The non-specific lipid transfer protein (nsLTP), Tri a 14, is a major allergen in one of the most common forms of occupational asthma: baker’s asthma. The disease is mainly caused by wheat flour inhalation. LTPs constitute a relevant family of plant food panallergens. These allergens show high resistance to heat treatment as well as proteolytic attack and are capable of inducing severe symptoms.
