Abstract

Η εφεύρεση περιλαμβάνει διαδικασία για εκχύλιση πρωτεΐνης-στόχου από κύτταρα Ε. coli η οποία περιλαμβάνει μείωση του pΗ διαλύματος ολόκληρων κυττάρων Ε. coli για να σχηματιστεί όξινο διάλυμα, διάσπαση των κυττάρων για να εκλυθεί η πρωτεΐνη στο όξινο διάλυμα, και διαχωρισμό των κυτταρικών κατάλοιπων από την εκλυμένη πρωτεΐνη για να αποκτηθεί πρωτεϊνικό προϊόν εμπλουτισμένο με την ετερόλογη πρωτεΐνη-στόχο. Η εφεύρεση περιλαμβάνει επίσης προσθήκη ενισχυτή διαλυτότητας.The invention comprises a process for extracting target protein from E. coli cells which comprises reducing the pH of whole E. coli cells to form an acidic solution, cleaving the cells to release the protein into the acidic solution, and separating the cell residues. the released protein to obtain a protein product enriched with the heterologous target protein. The invention also includes the addition of a solubility enhancer.
