Single Shot Intrasplenic Immunization: An Advantageous Procedure for Production of Monoclonal Antibodies Specific for Human Fibrin Fragments

Abstract
We describe the use of the single shot intrasplenic immunization technique as a particularly effective procedure for the production of specific monoclonal antibodies against a high molecular weight antigen. We found that with this technique several different, completely specific monoclonal antibodies could be produced against high molecular weight crosslinked fibrin degradation products. These results contrasted with those obtained using conventional multidose immunization, which only produced monoclonal antibodies that were cross-reactive with fibrinogen and/or noncrosslinked fibrin degradation products.
