Currently, 1-2% of people worldwide have this allergy, with a growing number of affected children in the US, Europe, and Australia. In the past decade, the prevalence of peanut allergy among children has doubled, which is concerning as the condition typically persists into adulthood. While symptoms of this allergy are usually mild to moderate, they can sometimes be severe and life-threatening, particularly in individuals who are highly sensitive. Even the smallest amount of peanut protein can trigger an allergic reaction in these patients. Oral ingestion is the most common method of exposure, but inhalation or skin contact can also cause symptoms. The reaction to peanut allergens is initiated by specific IgE antibodies that bind to receptors on the surface of mast cells and basophils. The crosslinking of these receptors by peanut protein can lead to mast cell and basophil degranulation, resulting in a range of allergic symptoms, including potentially fatal anaphylaxis.

You can tell the difference between the allergens by the last two numbers of their code.
  • .30 Purified mite bodies, this does not contain other material such as the faeces of the mites.
  • .50 Excrements of mites.
  • .60 A whole culture consist of all the material of the house dust mite cultivation. This means mite bodies, eggs, larves, cultivation medium and the faeces.
  • .71 purified Group 1 allergen (Der p 1 or Der f 1). Based on protein content (BCA).
  • .72 purified Group 2 allergen (Der p 2 or Der f 2). Based on protein content (BCA).
  • .85 Extract of whole culture. A whole culture consist of all the materials of the cultivation, including bodies, eggs, larvae, skin parts, cultivation medium and the excrements. This extract is most used by researchers.
  • .86 Purified extract of mite bodies.
  • .87 Excrements. These are purified excrements (faeces) of the house dust mites. We have excrement extracts available from D. farinae and D. pteronyssinus.
  • .95 Research Extract. Regular HDM extract but not filled out on dry weight but on protein content (BCA). These are small vials which are developed for researchers.
  • Our allergens will be delivered in freeze-dried (lyophilized) form. You can simply weigh the amount you need, dissolve the freeze-dried product in your buffer of choice and analyse your product.
    We do not add any proteins in the production process. 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 and these concentrations will not interfere with your process.
