| Outline of Final Research Achievements |
We recently developed a monoclonal antibody that shows strong temperature dependence in the binding to the epitope peptide, a carboxyl-terminal sequence of chicken CRY4.
In this study, we tested the possibility to use this epitope peptide as a tag for temperature-dependent affinity purification of the tagged-proteins. We found the binding of the antibody with epitope-tagged glutathione S-transferase (GST) and yellow fluorescent protein (YFP) in a temperature-dependent manner. We also succeeded in the temperature-dependent purification of those proteins.
This technology is the establishment of a new tag and purification methods of proteins, and also it would be applicable in a various fields to the temperature-dependent control of protein localization and function.
