"WebbHowever, more robust induction of proteins can be obtained by IPTG, a non-hydrolysable analog of lactose. Following expression, cells are lysed and total proteins are isolated. The induction of proteins will be monitored by separating proteins by SDS-PAGE. This is a technique for separating proteins based on their molecular weight.
