Recombinant allergens are essential tools in modern molecular allergology, enabling precise characterization of IgE-mediated immune responses and improving the accuracy of allergy diagnostics. Compared with natural allergen extracts, recombinant allergen proteins offer superior purity, batch-to-batch consistency, and well-defined molecular composition.
At Creative BioMart, we provide a comprehensive portfolio of recombinant allergens covering major allergen sources, including animal, plant, food, and fungal allergens. Our products support a wide range of applications, from basic allergy research to component-resolved diagnostics (CRD) and immunotherapy development.
Recombinant allergens are allergenic proteins produced through recombinant DNA technology using expression systems such as E. coli, yeast, or mammalian cells. These proteins replicate the structure and IgE-binding properties of natural allergens while eliminating variability associated with crude extracts.
Recombinant allergen proteins represent defined allergen components and are widely used in molecular allergy research to investigate sensitization patterns at the protein level. They are particularly valuable in component-resolved diagnostics, where individual allergen molecules are used to identify specific IgE responses.

Recombinant allergens provide significant advantages compared to traditional allergen extracts:
| Feature | Recombinant Allergens | Natural Extracts |
|---|---|---|
| Composition | Defined single proteins | Complex mixtures |
| Purity | High | Variable |
| Consistency | Excellent batch reproducibility | Batch variability |
| Specificity | Precise IgE-binding | Cross-reactivity risk |
| Safety | Low contamination risk | Possible impurities |
These advantages make recombinant allergens the preferred choice for standardized assays and advanced allergy diagnostics.
House dust mite allergens such as Der p 1 and Der p 2 are among the most studied IgE-binding proteins. They are major contributors to respiratory allergies and are widely used in IgE assays and CRD platforms.
Bet v 1, the major birch pollen allergen, is a key marker for pollen sensitization and cross-reactivity studies. Its homologs are commonly used to investigate plant-related allergy mechanisms.
Peanut allergens such as Ara h 2 are highly relevant in severe food allergy research. Recombinant forms are essential for studying IgE-binding epitopes and improving diagnostic specificity.
Fel d 1, the major cat allergen, is a dominant IgE-binding protein used in both diagnostic assays and environmental exposure studies.
Alt a 1 is a major fungal allergen associated with asthma and respiratory allergies. Recombinant fungal allergens support precise detection of mold sensitization.
| Animal-Derived Allergens | Including allergens from cats, dogs, rodents, and other animal sources, widely used in environmental and occupational allergy studies. |
| Plant and Pollen Allergens | Covering tree, grass, and weed pollen allergens such as Bet v 1 and Phl p proteins, critical for seasonal allergy research. |
| Food Allergens | Including peanut, milk, egg, and seafood allergens, supporting food allergy diagnostics and risk assessment. |
| Fungal Allergens | Derived from molds and fungi, these allergens are essential for studying respiratory and indoor allergies. |
