WebA method for the preparation of model immune complexes of heat-aggregated human IgG with predetermined molecular masses is described. IgG complexes with different molecular masses were produced by incubation of human IgG for 20 min at 63 degrees C, the protein concentration varying from 0.5 to 5 mg/ml before heat treatment. WebPreferably, the preparation includes multimeric IgA and is essentially free of IgG in its various forms. Other compounds, such as antibiotics, antiphlogistic agents and antacids, also may be administered. Immunoglobulin A may also be used in …
In contrast, heating of IgG at 63°C for 30 minutes is a widely used method to produce soluble IgG aggregates. Such aggregates possess many biological properties which make them suitable for use as controls in studies concerning soluble antigen-antibody complexes. WebIt is concluded that among cells bearing Fcγ or Fcα receptors, only T cells were inducible into suppressor cells by the binding of the matching immunoglobulin class. A short exposure of human peripheral blood mononuclear cells (PBMC) to heat‐aggregated IgG (or IgA) was found to inhibit pokeweed mitogen (PWM)‐induced human B cell differentiation into IgG …
