Objectives Autoantibodies against post-translationally modified proteins (anti-modified protein antibodies or AMPAs) are a hallmark of rheumatoid arthritis (RA). A variety of classes of AMPAs against different modifications on proteins, such as citrullination, carbamylation and acetylation, have now been ...
Monoclonal antibodies targeting a variety of epitopes have been isolated from individuals previously infected with SARS-CoV-2, but the relative contributions of these different antibody classes to the polyclonal response remains unclear. Here we use a yeast-display system to map all mutations to the ...
To assess the diagnostic value of antibody activities to Trichosporon cutaneum antigen in patients with summer-type hypersensitivity pneumonitis in Japan, we measured the serum IgG, IgA, and IgM antibodies to saline-soluble antigen of homogenized T. cutaneum cells by enzyme-linked immunosorbent assay ...

A variety of classes of AMPAs against different modifications on proteins, such as citrullination, carbamylation and acetylation, have now been ...
Antibodies are divided into different classes and subclasses (isotypes) according to structural differences in the constant region of the heavy polypeptide chains. The different isotypes mediate specific biologic functions that are important for the response to pathogens and in the pathogenesis of immunol...
The capacity of mouse IgM, IgGl, IgG2 and IgA anti-dinitrophenyl (DNP) antibodies to activate mouse or guinea-pig complement was studied, using a sensitive haemolytic assay and two-dimensional immunoelectrophoresis to detect cleavage of mouse C3. Three monoclonal IgM antibodies, and a heterogeneou...
The binding of highly purified anti-nucleoside antibodies to fixed metaphase chromosomes of the kangaroo rat (Dipodomys ordii) revealed the presence of different classes of DNA in different regions of the chromosomes. To permit antibody binding, the chromosomal DNA was first made single-stranded by ...
Classes of Antibodies IgM and IgD are two classes of antibodies. They are found on the surface of mature B cells. If a B cell encounters an invader with antigens that match its antibodies (like a key in a lock), the antigen is brought inside and then displayed on the surface, akin to...
Immunoglobulins belonging to different classes were identified by means of IEA. Examination of 514 patients with different forms of brucellosis and 122 controls demonstrated the high specificity and sensitivity of IEA for detecting antibodies of different physiochemical nature. The use of IEA made it ...
CHANGES IN ЕLASTIN TURNOVER IN PATIENTS WITH DIFFERENT TYPES OF HYDATID DISEASE (ECHINOCOCCOSIS) The aim of this study was to assess elastin turnover via changes in levels of specific antielastin antibodies (AEAbs) of different immunoglobulin classes (IgM, IgA, IgG) and IgG subclasses in sera...
