The molecular allergens available for component resolved diagnosis for hen eggs.

Hen Eggs Allergen Name Features
nGal d 1
(Ovomucoid)

  • White-serine protease inhibition activity with high resistance to heating and chemical denaturation

  • Highly allergenic, correlated to high risk for reaction to all forms of egg
nGal d 2
(Ovalbumin)

  • Serine protease inhibitor, heat-labile

  • it is the most abundant egg white protein

  • It is correlated with risk for clinical reaction to raw or slightly heated egg and certain vaccines
nGal d 3
(Conalbumin)

  • low resistance to heating and chemical denaturation
nGal d 5 *

  • Hen yolk/chicken meat

* Available only for semiquantitative methods.
