Iptg sonication
WebExpression of aSyn from inducible promotors is initiated using IPTG. Although several labs induce protein expression for four hours, others induce for shorter periods or up to 16 h. In addition, the IPTG concentration used varies and, in some protocols, it is not used at all, or not clearly stated. Web1 I follow a protocol to get protein from E.coli cells after sonication. I used to grow 6 litres of large cultures and add IPTG to express the protein. I centrifuge for 10 mins at 8,000 rpm and get the pellets. Then I do sonication and centrifuge again at 20,000 for 1 hr.
