| Outline of Final Research Achievements |
To establish a new ELISA that detects polymeric osteopontin, which we previously found as a chemoattractant for neutrophils, we attempted to obtain polymeric OPN specific monoclonal antibodies. First we generated mice that express only polymerization-incompetent OPN by introducing some mutations into the OPN gene. The mice produced many antibody clones responding to injected polymeric OPN. However, many of clones recognized wild type OPN, which prevent us from establish the specific clones. Probably, immunological tolerance was not sufficient for the mice not to respond wild type OPN. We restarted to generate the tolerant mice by CRISPR-Cas9 method.
