BACKGROUND House dust mite (HDM) allergen quantification in house dust samples before and after the allergen elimination is one means of convincing the target population about the health benefits of allergen removal from their environment. OBJECTIVE To produce local reagents for quantification of Der f 1 (major allergen of Dermatophagoides farinae) in dust samples from houses of HDM allergic ...

Annexin II (Annexin A2, ANXA2) is a 36 kDa calcium-dependent phospholipid-binding protein that is located on the surface of most eukaryotic cells. ANXA2 is involved in several biological processes, including anti-inflammatory effects, Ca27+-dependent exocytosis, immune responses, Ca2+ transport and phospholipase A2 regulation. In our previous study, ANXA2 was identified as an up-regulated gene ...

Rheumatoid arthritis (RA) and spondyloarthritis (SpA) are chronic diseases characterized by activation of the immune system and production of antibodies. Thus, rheumatoid factor, anti-animal IgG antibodies and heterophilic antibodies in plasma samples from arthritis patients can interfere with immunoassays such as sandwich enzyme-linked immunosorbent assay (ELISA) systems often used in arthriti...
