Part Descriptions
LP13994-6 Dermatophagoides farinae
The most important House dust mites are Dermatophagoides farinae, which is more common in drier areas, and D. pteronyssinus. D. farinae has many of the same characteristics as D. pteronyssinus, which co-exists with the Storage mite Blomia tropicalis in subtropical and tropical regions as a major source of allergens. Recent evidence shows that even these very general boundaries are blurring and that in many instances all 3 mite species may be highly relevant, causing frequent sensitisation.
House dust mites cause symptoms such as perennial-type asthma, rhinitis and conjunctivitis, often with nocturnal or early morning episodes

LP13994-6 Dermatophagoides farinae
Dermatophagoides farinae, a species of house dust mite, is found worldwide but most abundant in drier regions. PMID: 15553602 Groups I and II, Der f 1 and Der f 2, are the most important allergenic proteins in D. farinae and exist as a number of isoforms. The recombinant forms, rDer f 1 and rDer f 2, are highly homologous to the native forms. PMID: 2732406

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]
