IgG3, κ from murine myeloma was used as blocking agent in immunofluorescence labeling of larval and adult Echinococcus multilocularis worms. It was used as negative control in assay to study the surface binding of antibodies to meningococci.
IgG antibody subtype is the most abundant serum immunoglobulins of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defence of the neonate against infections. IgG3 is the has a unique extended hinge region conferring greater flexibility
IgG3, κ from murine myeloma specifically recognizes mouse IgG3. Specificity of the mouse IgG3, κ is determined by immunodiffusion and IEP techniques. The purified myeloma preparation is non-reactive with antisera to mouse IgA, IgM, IgD, IgG1, IgG2a and IgG2b.
