In patient biopsies, little to no loss of AChRs density and structure, IgG deposition, or complement was observed [67,68]. These studies, however, investigated the intercostal muscle and biceps brachii muscle, which are likely less affected by MuSK antibodies. A number of MuSK MG patients ...
Activation was determined based on the expres- sion of vascular cell adhesion molecule-1 (VCAM-1) and inter- cellular CAM-1 (ICAM-1) measured by flow cytometry. Cells were treated with hTNFa that induces upregulation of VCAM-1 and ICAM-1, as a positive control. The antibodies and ...

Monoclonal antibodies are increasingly used to prevent and treat viral infections and are pivotal in pandemic response efforts. Antibody-secreting cells (ASCs; plasma cells and plasmablasts) are an excellent source of high-affinity antibodies with therapeutic potential. Current methods to study antigen-...
Affinity purification against the immobilized protein of interest can be useful to increase the specificity of polyclonal antibodies. Most often, indirect immunolocalization methods are employed in which a primary antibody is allowed to react with the fixed cell material. After removal of unbound ...
The heavy chain also serves to determine the functional activity of the antibody molecule. There are five antibody classes—IgG, IgA, IgM, IgE and IgD—which are distinguished by their heavy chains γ, α, µ, ε and δ, respectively (Figure 2). The IgD, IgE and IgG antibody classes ...
Immune complexes of polyclonal antibodies and a soluble antigen, which are formed during a typical immune response, are usually cleared by phagocytic cells. Depending on the antigen to antibody ratio, the complexes can be like soluble lattice or like large insoluble particles, which are deposited in...
of betacoronaviruses including SARS-CoV, SARS-CoV-2, MERS-CoV and the endemic human coronavirus HCoV-OC43. Both cross-reactive antibodies target the stem helix in the spike S2 fusion subunit which, in the prefusion conformation of trimeric spike, forms a surface exposed membrane-proximal helical...
purification of mammalian seral • We have attempted to use this method to purify chicken antibodies to either beof serum albumen (BSA) or Bryan strain Rous sarcoma virus (BS-RSV) for use ill the reversed bisdiazobenzidine teohnique2, a method of passive haemagglutination which detects ...
Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS), the etiology of which is poorly understood. The most common laboratory abnormality associated with MS is increased intrathecal immunoglobulin G (IgG) synthesis and the presence of oligoclonal ...
