    Description

    Purified D. pteronyssinus:

    • Der p 1 purified allergen (≥ 95%) Approximately 400-500 µg BCA per vial. Group 1 (Der p 1) allergens have a molecular weight of 25 kDa, as monomer, neutral slightly acidic, and polymorph proteins. Citeq can extract the Group 1 allergens with a purity of ≥ 95%. At least 70% of allergic individuals recognize group 1 allergens. These allergens are identified in a lot of house dust mites (HDM). The allergens can be conceded through the whole body, but are mostly present in the feacel pellets of the HDM. The major allergen Der p 1 is mostly used in in-vitro diagnostic tests and in allergy and asthma research.
    • Der p 2 purified allergen (≥ 95%) (currently out of stock)
      Approximately 200-300 µg BCA per vial. Group 2 (Der p 2) allergens are neutral to slightly basic and polymorph. Citeq can extract the Group 2 allergens with a purity of ≥ 95%. The majority of allergic individuals recognize the 14kDa non-glycosylated allergens. Group 2 allergens are identified in a large number of HDM’s compared to other allergens. Group 2 allergens are abundantly present within the mite body. The major allergen Der p 2 is mostly used in in-vitro diagnostic tests and in allergy and asthma research.

    Our specialty is the production of house dust mites and their allergens. Our strength lies in the control of the whole chain, from cultivation to purification. Our specialty starts with our cultivation medium which has an absolute low in foreign protein. Our cultivation technique leads to high concentrations of the major allergens, resulting in strong raw materials, extracts in several grades of purity, and very pure major allergens. All our house dust mite products contain the native proteins, with no denaturing treatments during production and purification.

    • We also have the D. pteronyssinus available in the following forms: D. ptersonyssinus extract and D. ptersonyssinus whole culture
