LP17546-0   Ovalbumin
Gal d 2, also known as Ovalbumin and Albumin, is a 44 kDa phosphoglycoprotein.

Ovalbumin is a major allergen of Hen's egg white and is the most abundant of Egg white proteins, comprising 54% of the total proteins and a fivefold greater quantity than Ovomucoid.

Ovalbumin was previously considered to be the most important allergen of Egg white. But its importance was over-estimated due to frequent contamination of commercial preparations with Ovomucoid. In spite of a difference in the molecular weights of Ovomucoid and Ovalbumin, they cannot be completely separated by some processes, which has lead to the erroneous assumption of cross-reactions.

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] Source: Regenstrief LOINC
