Method for the extraction of periplasmic proteins from prokaryotic microorganisms in the presence of arginine

The invention relates to the use of arginine as an agent for the extraction of recombinant periplasmic proteins. The invention further relates to a method for the extraction of a periplasmic protein of interest, which consists in: (i) suspending the pellet of cells or cell debris from cells originat...

Beschreibung
Zusammenfassung:	The invention relates to the use of arginine as an agent for the extraction of recombinant periplasmic proteins. The invention further relates to a method for the extraction of a periplasmic protein of interest, which consists in: (i) suspending the pellet of cells or cell debris from cells originating from the culture of a prokaryotic microorganism, transformed by means of an expression vector containing a gene coding for the said protein and means for its expression in the periplasm of the said microorganism, in a buffer solution containing arginine; and (ii) recovering the protein of interest in the supernatant of the bacterial suspension thereby obtained.
