House dust mite allergens
House dust mites are arachnoids and are present in every household and are living within dust, textile, carpets, beds and upholster furniture. HDMs belong to the Pyroglyphidae family. The most important House dust mites are Dermatophagoides pteronyssinus and Dermatophagoides farinae (in drier areas). HDMs contain allergens which is a (non) protein or substance which can induce an allergic response. Humans mostly get exposed to house dust mites and other indoor allergens. Humans who are atopic can react on this exposure by developing an allergy. Allergic responses can result in eczema, conjunctivitis, asthma symptoms and rhinitis.
Supplier of HDM allergens
Our main focus is the production of house dust mites (HDMs) and their allergens. Citeq was born based on a passion for mites and the research for how mites influence our daily lives. Our founders and leading scientists have pharmaceutical, biological and biochemical backgrounds. With over 25 years of experience and an extensive knowledge about mites Citeq is more than just a supplier of allergen source material. We strive for an academic collaboration with our customers in order to achieve the best possible results in research, diagnostics and immunotherapy.
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 deliver house dust mites source material in different forms such as whole culture, purified form (Der p 1/ Der p 2/ Der f 1/ Der f 2) and extracts. Please click on the type of house dust mite that you are interested in for more information and the available forms.
Certificate of analysis
Each product will be delivered with a certificate of analysis. The certificate of analysis provides information, e.g. allergenic pattern, protein content (BCA and Bradford method), endotoxin level, protein pattern and protease activity. On this page you can find an an example of this certificate. If you want to receive a certificate of analysis before ordering please let us know. We shall send you the certificates of multiple batches so you can compare the batches and choose the batch that meets your requirements.
We understand that if you are using source material which is fulfilling your wishes you would like to receive the same material again for future projects. To provide material from the same batch over a longer period of time we produce large batches. This way we have we a lot of material available from a specific batch. You can even place a reservation for future orders.
HDM induced asthma models
Often we receive questions about house dust mite (HDM) induced asthma models. Which models are researchers using, which model do we recommend, what are the differences? To answer these questions we have contacted multiple research institutes all over the world and collected their models and background information.
