D. pteronyssinus/ D. farinae HDM mix

Because D. pteronyssinus and D. farinae house dust mites are the most studied species we have developed a mixture of both species. The mixture is available as an extract but also as a whole culture of mites. Dermatophagoides farinae and Dermatophagoides pteronyssinus are insects from the class arachnid and combined with Euroglyphus maynei these 3 species account for 70-92% of the mites which are present in households. House dust mites are the most prevalent source of indoor allergens. Approximately 1-2% of the world population suffers from house dust mite allergy. Studies across the US, Europe, Asia, South America, New Zealand, Australia and Africa have shown that the house dust mites are present globally.

The HDM mix is available in the following forms:

  • HDM mix extract (of whole culture), vials of 10 or 100 mg
  • HDM mix whole culture (vial of 1 gram) - active pharmaceutical ingredient

Our products will be delivered in freeze-dried (lyophilized) form. Please contact us for pricing and availability.

House dust mite allergens

Our main focus is the production of house dust mites (HDMs) and their allergens. We deliver the D. pteronyssinus and D. farinae HDM in different forms. The most popular form is the regular HDM extract but we can also deliver whole cultures, purified allergens, excrements and mite bodies.

In our production process we do not add any proteins. The only compound we use in our products which is not strictly from mites is the medium where the mites feed on. This medium contains an absolute low number of non-mite proteins. We try to cultivate the mites with the lowest amount of bacteria and moulds possible. All our house dust mite products contain the native proteins, with no denaturing treatments during production and purification.
