Molecular and allergenic characterization of recombinant tropomyosin from mud crab Scylla olivacea.

Background: Tropomyosin is a major allergen in crustaceans, including mud crab species, but its molecular and allergenic properties in Scylla olivacea are not well known. Thus, this study aimed to produce the recombinant tropomyosin protein from S. olivacea and subsequently investigate its IgE reactivity.

Identification of Common and Novel Major Crab Allergens in Scylla tranquebarica and the Allergen Stability in Untreated and Vinegar-treated Crab.

Crab allergy is reported as a serious form of food allergy in many countries. This study was aimed to identify the major allergens of the local mud crab, Scylla tranquebarica (S. tranquebarica), and subsequently, determine the effect of vinegar treatments on the crab allergens.
