Plant allergens are essential tools for studying allergic diseases, developing diagnostic assays, and advancing immunotherapy research. At Creative BioMart, we provide a comprehensive portfolio of plant allergen proteins, including recombinant and natural allergens derived from pollen, food, and other plant sources, to support academic and industrial research worldwide.
Whether you are working on IgE-mediated allergy mechanisms, cross-reactivity studies, or diagnostic kit development, our high-quality plant allergens offer reliability, consistency, and scientific accuracy.
Plant allergens are proteins or glycoproteins derived from plants that can trigger IgE-mediated immune responses in sensitized individuals. These allergens are commonly found in pollen, fruits, vegetables, nuts, and latex, and are responsible for a wide range of allergic reactions, including allergic rhinitis, asthma, and food allergies.
At the molecular level, plant allergens are recognized by IgE antibodies, leading to immune activation and clinical symptoms. Due to their well-defined structures and immunological relevance, plant allergens are widely used in allergy diagnostics, immunotherapy research, and epitope mapping studies.

Classification of Plant Allergens
Plant allergens can be classified based on their protein families, structural properties, and biological functions. Understanding these classifications is essential for studying allergen cross-reactivity and selecting appropriate targets for research.
These allergen families play critical roles in cross-reactivity between different plant species, which is a key focus in allergy research.
Common Plant Allergens List
Plant allergens originate from various sources, including pollen and plant-derived foods. Below are some commonly studied plant allergens:
Pollen Allergens
Bet v 1 – Birch pollen allergen (PR-10 family)
Phl p 5 – Timothy grass allergen
Amb a 1 – Ragweed allergen
Food Allergens (Plant-Derived)
Ara h 1, Ara h 2 – Peanut allergens
Gly m 4 – Soybean allergen
Pru p 3 – Peach allergen (LTP family)
Latex-Related Allergens
Hev b allergens – Natural rubber latex proteins
These allergens are widely used in diagnostic assays, allergen standardization, and immunological studies.
Recombinant vs Natural Plant Allergens
Selecting the right type of allergen is critical for experimental success. Both recombinant and natural allergens offer unique advantages:
Feature
Recombinant Plant Allergens
Natural Plant Allergens
Source
Expression systems (E. coli, yeast, etc.)
Extracted from native plant materials
Consistency
High batch-to-batch consistency
May vary depending on source
Purity
Highly controlled
May contain natural isoforms
Application
Research, diagnostics, assay development
Clinical relevance, validation studies
Recombinant allergens are often preferred for standardized assays, while natural allergens are valuable for physiological relevance.
Applications of Plant Allergen Proteins
Plant allergen proteins are indispensable in both basic research and industrial applications:
Allergy Diagnostics
Used in IgE binding assays, ELISA, and component-resolved diagnostics (CRD)
Immunotherapy Development
Support allergen-specific immunotherapy (AIT) research and vaccine design
Epitope Mapping
Identify IgE-binding regions and antigenic determinants
Cross-Reactivity Studies
Investigate molecular similarities between allergens across species
With increasing demand for precision medicine, plant allergens play a crucial role in improving diagnostic accuracy and therapeutic outcomes.

Frequently Asked Questions
Q1: What are common plant allergens?
A: Common plant allergens include pollen allergens such as Bet v 1 from birch and Phl p 5 from grass, as well as food allergens like Ara h 1 and Ara h 2 from peanut.
Q2: What is the difference between recombinant and natural allergens?
A: Recombinant allergens are produced using expression systems and offer high consistency, while natural allergens are extracted from plant sources and better reflect native biological conditions.
Q3: What are plant allergens used for?
A: Plant allergens are widely used in allergy diagnostics, IgE binding assays, immunotherapy research, and epitope mapping studies.
Q4: What is Bet v 1?
A: Bet v 1 is a major birch pollen allergen belonging to the PR-10 protein family and is one of the most extensively studied plant allergens due to its strong IgE reactivity.
Q5: How do I choose the right plant allergen for my research?
A: The choice depends on your application, such as diagnostics or immunotherapy research, and whether recombinant or natural allergens are required.
