Hi all,
I would like to ask, if two sgRNAs are mixed together at fixed ratio without Cas9 enzyme, say 1:1, how long can they be stored at -20 degrees before use? Should they be used immediately or can be stored upon the next use?
I am looking for literature reviews focusing on public sector organizations capabilities for participating in and coordinating innovation together with both private and non-governmental organizations
