Recombinant allergens

Constant need for improvements in allergy diagnosis and treatments go hand in hand with need of precisely defined allergen detection methods relied on excellent quality, pure and stable allergic raw materials.

Recombinant allergens stand out as reliable, high purity product, compared to allergen extracts they’re clear of non-allergenic impurities or contamination by other allergens, which could possibly lead to false-positive results.

EXBIO is a primary manufacturer of recombinant allergens since 2020, when EXBIO has acquired Apronex in order to meet growing customer demands specifically on allergy-screening assays. Our recombinant allergens are produced in suitably chosen expression systems (both in prokaryotic and in eukaryotic), accordingly to the nature of each particular allergen, followed by at least 2 sequential chromatography purification steps, by which high product purity is ensured.
Lot-to-lot consistency is ensured by outstanding level of product development, manufacture and QC control (ISO 9001:2015 certified Quality Management System).

Recombinant allergens are in our permanent offer, immediately ready in stock as a standard catalogue products, available also for OEM and in a BULK amount as well.

If you're seeking assays developers and vendors our excellent quality recombinant allergens are intended for you either for a research use or for developing/manufacturing of a commercial products. We’re happy to assist you with any technical queries and further custom services.

As they‘re one of key reagents for allergen identification, their sale not only within the OEM is on the rise.
EXBIO projects and manufactures more than 30 recombinant allergens covered Animal, Food, House dust mite, Pollen, Mold and Venom allergens.
