Part Descriptions
LP17619-5 Pecten spp
Scallops, or fan shells, are found in all seas, both shallow and deep. There is some cross reactivity between crustaceans and mollusks. Allergic reactions include urticaria, angioedema, gastrointestinal distress, asthma, rhinitis, and anaphylaxis, and also severe allergic reactions, requiring emergency treatment. Sera shows IgE activity to a 38kD protein present in boiled muscle extracts of all mollusks, and these results suggest that the heat-stable 38kD protein is the major cross-reactive allergen present in crustaceans and mollusks, identified as the muscle protein tropomyosin. Immunoblot inhibitions have demonstrated up to 28% bi-directional cross-reactivity between shrimp and scallops, further confirming the major cross-reactive antigen as the respective tropomyosins of shrimps and scallops. It has been noted that many patients allergic to shrimp do not show clinical hypersensitivity reactions to mollusks or other seafood, indicating the existence of genus specific antigens. The allergen code is f338.

LP32397-9 Ab.IgG4
IgG4 is the least common subtype of IgG, and it has a variety of functions. In the context of allergic disease it is thought to have an immune-inhibitory role in preventing anaphylaxis and is commonly known as a "blocking" antibody. IgG4 binding to an allergen can compete with IgE-mediated binding, thereby inhibiting the activation of mast cells and basophils and IgE-mediated presentation to T-cells. Measuring IgG4 and its ratio to IgE has a role in monitoring allergen specific immunotherapy PMID: 26023323. IgG4 is also thought to have a role in autoimmunity and be involved in a less defined entity known as IgG4-Related Disease, a chronic immune-mediated fibroinflammatory disorder that often manifests with tumor-like masses .https://www.merckmanuals.com/professional/musculoskeletal-and-connective-tissue-disorders/igg4-related-disease/igg4-related-disease
