A Bead-Based Nonradioactive Immunoassay for Autoantibody Testing in a Mouse Model of Myasthenia Gravis
Serological testing for anti-acetylcholine receptor (AChR) autoantibodies is not only crucial for the diagnosing, disease monitoring, and treatment management of patients with myasthenia gravis (MG) but also for preclinical studies utilizing MG disease models. However, there are no specific guidelines on which methods to use in clinical diagnostic or research laboratories to detect or quantify any MG-specific autoantibodies. Conventional autoantibody assays, particularly those for anti-AChR antibodies, are varied and mostly laboratory-specific. Here, we report our new nonradioactive immunoprecipitation–immunoblotting method for assessing autoantibodies (anti-AChR antibodies) in a mouse model of MG. This simple, efficient, reproducible, and cost-effective assay appears superior to the enzyme-linked immunosorbent assay but comparable to the radioimmunoprecipitation or cell-based assay in specificity and sensitivity. Thus, the newly developed assay can serve as a valuable alternative to classical assays and is suitable for routine testing of AChR-specific autoantibodies in preclinical studies. The further optimization of our assay may facilitate its application in the diagnosis and therapeutic management of patients with MG.
期刊介绍:
Antibodies (ISSN 2073-4468), an international, peer-reviewed open access journal which provides an advanced forum for studies related to antibodies and antigens. It publishes reviews, research articles, communications and short notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. Electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material. This journal covers all topics related to antibodies and antigens, topics of interest include (but are not limited to): antibody-producing cells (including B cells), antibody structure and function, antibody-antigen interactions, Fc receptors, antibody manufacturing antibody engineering, antibody therapy, immunoassays, antibody diagnosis, tissue antigens, exogenous antigens, endogenous antigens, autoantigens, monoclonal antibodies, natural antibodies, humoral immune responses, immunoregulatory molecules.
