[ccp4bb] Solubilization refolding percentage efficiency

2011-02-10 Thread megha goyal
Hello, Can anyone let me know how to calculate solubilisation and refolding efficiency. We perform solubilisation and then refolding and check by HPLC if refolding is completed or not [single peak on HPLC]. how do i determine % efficiency of refolding. kindly guide me. regards, megha

How: 1. measure total protein before refolding (eg by absorbance at 280) 2. Purify refolded fraction by gel filtration in FPLC 3. measure total protein after refolding 4. calculate efficiency ... Why? I don't see the reason to know the efficiency. If after refolding I would get enough in a
