Abstract

Tropomyosin (TM) is a major allergen in shellfish, known to cross-react with mite, cockroach and/or some roundworm (nematode) TM. In this study, we aimed to express and purify TM from the parasitic nematode Anisakis pegreffii and also to characterise its cross-reactivity with TM from shellfish. A. pegreffii was isolated from the flathead tiger fish (Neoplatycephalus richardsoni) and characterised using single-strand conformation polymorphism (SSCP)-based sequencing of the first and second internal transcribed spacers (ITS-1 and ITS-2) of nuclear ribosomal DNA. The recombinant tropomyosin (rTM) of A. pegreffii was expressed, purified and confirmed by immunohistochemistry, sequencing and LC-MS..
