Allergen source materials
We produce insect and mould allergens for professionals in the field of allergy and asthma. The cultivation technique we use leads to high concentrations of the major allergens, resulting in strong raw materials, whole cultures, extracts and purified major allergens.
Effective SCIT using purified allergens in a murine asthma model Does the use of purified major house dust mite allergens (Der p 1 & Der p 2) in a murine asthma model achieve superior suppression of allergic manifestations compared to an allergen extract? This is the...read more
Introduction On this page we describe the results for determining the solubility of HDM extracts. We have dissolved the Dermatophagoides pteronyssinus extract FD (freeze-dried) and whole culture D. farinae extract FD (freeze-dried) in 70% DMSO. We have compared this...read more
Products produced by Citeq Biologics are stored at -20°C and transport of these products occurs at ambient temperatures. Therefore, long term stability studies are performed at -20°C and short term stability studies are performed at ambient temperature (transport). In...read more
Improper reconstitution of lyophilized (freeze-dried) allergenic extracts can cause variations in allergen content of the same extract after reconstitution and should be avoided. Customers who have used our mould (fungi) extracts had questions about how to dissolve...read more
Because D. pteronyssinus and D. farinae house dust mites are the most studied species we have developed a mixture of both species. The mixture is available as an extract but also as a whole culture of mites. Dermatophagoides farinae and Dermatophagoides pteronyssinus...read more
House dust mites (HDMs) are arachnoids and belong to the Pyroglyphidae family. HDMs are present in every household, living within dust, textile, carpets, beds and upholster furniture (Colloff, 2009). Humans get exposed to HDMs allergens and other indoor allergens on a...read more
