- To establish a screening process for identifying bacterial clones expressing soluble protein.
- To streamline the validation and preparation of protein stocks for structural genomics.
Main Methods:
- Development of methods for producing expression constructs in a 96-well plate format.
- Implementation of a screening process to identify bacterial clones expressing soluble protein.
- Application of semi-automated methods for solubility validation and freezer stock production.
Main Results:
- An 80% success rate was achieved in identifying clones producing soluble protein.
- Significant reduction in labor for validation and freezer stock preparation.
- A plate map was generated to locate wells with soluble protein-producing clones.
Conclusions:
