Dermatophagoides pteronyssinus extract
Extract of Dermatophagoides pteronyssinus whole culture. Extracts are applied in in-vitro diagnostics tests and as standards or active substance in the research of asthma and allergy.
Our D. pteronyssinus house dust mites products are used by researchers all over the world. We have the D. pteronyssinus HDM available in different forms. The most popular form is the regular D. pteronyssinus extract but we can also deliver whole cultures, purified allergens (Der f 1/ Der f 2), 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. Our main focus is the production of house dust mites and their allergens.
