For vacuum lyophilization of proteins, are volatile MS buffers like ammonium bicarbonate suitable, or their "volatile" properties only applies in ESI spray, while in lyophilization the salt behaves as any other compound and simply concentrates?
I would like to know how to register the journal Flora Montiberica (ISSN 1138-5952 - eISSN 1988-799X) in Research Gate.
