Allergenicity assay of allergen from Dermatophagoides farinae in transgenic tobacco.

Derf₂ gene for one of mite allergens in Dermatophagoides farinae has been cloned and expressed under regulation of 35S promoter in transgenic tobacco. The transcriptional analysis showed that this mite complete gene structure in genomic sequence could be spliced at prediction site. Allergenicity assay with immunological sera indicated that the extracts from the transgenic tobacco gave obvious positive IgE binding reaction with specific serum pool. This work would be of potential use in allergenicity assessment of genetically modified food. [ABSTRACT FROM AUTHOR]
