Protein A reactivity of two distinct groups of human monoclonal IgM

Scandinavian Journal of Immunology
I LindI Fölling


Fifteen human monoclonal IgM proteins could be divided into two groups based on their ability to inhibit binding of a labelled human monoclonal IgM (IgM-Se) to Staphylococcus aureus Cowan 1 (IgM-Se assay); seven were positive and eight were negative. We found complete agreement between positive reaction in the IgM-Se assay, the presence of protein A reactivity in gel diffusion experiments, and high titres in an indirect haemagglutination test detects antibodies to protein A-IgG complexes. The protein A precipitation patterns of IgM and autologous IgG were not identical.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
