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.
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
House dust mites are a major source of allergens and a major contributor to allergic diseases such as asthma, rhinitis, and atopic dermatitis. House dust mite excrements are considered the main source of allergy (1). More than 95% of the allergen accumulating in mite...read more
Our products are used by researchers and diagnostic companies all over the world. We ship our products with FedEx to your country of choice.
Because of our quality system we produce high quality allergen extracts. Our products will be delivered with a certificate that specifies the amount of allergens, level of endotoxin and much more.
