The Durham Osmolyte Screen
This new screen is the third Durham screen developed. The Durham Osmolyte Screen (MD1-120, 96 x 0.5ml) lets you test which of over 50 osmolytes (carbohydrates, amino acids, polyols and NDSBs) helps stabilize your protein of interest. Osmolytes can be an advantage as they
- often stabilize proteins as they are commonly present in the native protein environment
- rarely affect protein function due to their neutral chemical characteristics
- are uncharged, highly soluble organic molecules accumulated by microorganisms to balance high salt external environments
You can combine the Durham Osmolyte Screen with the Durham Salt Screen and the Durham pH Screen for a more complete testing of your protein's crystallization environment. The screen data can then easily be analyzed with NAMI, a free-to-download GUI-based software.
