Background: Der p 23 was recently identified in a European population as a major allergen and potentially a chitin binding protein.

Although the primary sequence of the major allergen Len c 1 is known, the location of the IgE-binding epitopes remains undefined.

A cDNA expression library was constructed from whole ticks and screened with a polyclonal rabbit antiserum raised against the major allergen.

Bla g 1 is a major allergen from Blatella germanica and one of the primary allergens used to assess cockroach allergen exposure.

However, the 31 kDa major allergen was extracted in about the same amount, either by incubation or by cell breakage of the cells.

The proteins with molecular weights ranged from 5.0 x 10(3) to 43 x 10(3) were the major allergen with strong allergenicity and immunogenicity.

Thus, these antigens can be considered as major allergens.

Background: The major allergens in fish are parvalbumins.

From now on, food manufacturers must clearly label their products if they contain any of 12 major allergens.

Background: Identification of potential T-cell epitopes in the peanut major allergens is essential for development of peptide-based immunotherapy.

We performed this study to identify major allergens of rice and changed allergenicity in cooked and hypoallergenic rice.
