Antibodies is an international, peer-reviewed open access journal that 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 are no restrictions on the length of the papers, and full experimental and/or methodological details must be provided. Electronic files or software regarding the full details of the calculations and experimental procedures—if unable to be published in a conventional manner—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, and immunoregulatory molecules.
