Egg allergens

Egg allergens

Egg allergens are key triggers of pediatric IgE-mediated food allergy and are also relevant in occupational exposure, particularly in bakery and food-processing settings. Most clinically relevant IgE responses target egg white (albumen), while egg yolk allergens are mainly associated with bird–egg syndrome due to cross-reactivity with avian serum proteins.

Major egg white allergens include ovomucoid (Gal d 1), ovalbumin (Gal d 2), ovotransferrin (Gal d 3), and lysozyme (Gal d 4), all recognized by WHO/IUIS. Ovomucoid is strongly linked to persistent allergy due to heat and digestion stability, whereas ovalbumin is the most abundant sensitizing protein. Ovotransferrin and lysozyme show moderate and occupational relevance, respectively.

These allergens are widely used in research, diagnostics, and food safety testing. Recombinant and native proteins support IgE assays, and component-resolved diagnostics (Gal d 1–5, including α-livetin/Gal d 5) improve allergy profiling and risk assessment.

Key Egg Allergens & Biological Significance

  • Ovomucoid (Gal d 1): major clinically relevant allergen; heat-stable; digestion-resistant; associated with persistent allergy.
  • Ovalbumin (Gal d 2): most abundant egg white protein; heat-labile; important sensitizing antigen.
  • Ovotransferrin (Gal d 3): iron-binding glycoprotein; moderate allergenicity.
  • Lysozyme (Gal d 4): antimicrobial enzyme; relevant in occupational exposure and food additive contexts.

Common Reagents & Analytical Tools

  • Recombinant and native egg white proteins for IgE binding and immunoassays.
  • Monoclonal/polyclonal antibodies targeting ovomucoid and ovalbumin.
  • ELISA and multiplex immunoassay kits for allergen quantification and compliance testing.
  • Serum IgE assays and component-resolved diagnostic panels (egg white and yolk allergen profiling).

Key Features for Research Use

  • High-specificity allergen detection systems (ELISA, FEIA, multiplex IgE platforms).
  • Stable marker targeting (notably ovomucoid) for processed food analysis.
  • Standardized reagents enabling reproducible immunological and diagnostic studies.
  • Applications in food safety, clinical allergy diagnostics, and occupational exposure assessment.
