Supplier of allergen products
Citeq specializes in the production of mite, mould, food and insect allergens. Our strength lies in the control of the whole chain, from cultivation to purification.
We produce allergenic extracts and whole cultures for researchers and diagnostics. Our main focus is house dust- and storage mites, but we have a broad assortment of allergens from insects, cockroaches, moulds and food. We have several forms on stock such as whole cultures, extracts, purified allergens and excrements. Our products are used by researchers and diagnostic companies all over the world.
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 mite products contain the native proteins, with no denaturing treatments during production and purification.
