Fig. 2From: Construction and characterization of immunoliposomes targeting fibroblast growth factor receptor 3Inducible expression and purification of rScFv-Cys. a SDS-PAGE analysis of rScFv-Cys. M, Marker. Lane 1, total bacterial protein without IPTG. Lane 2–7, total bacterial protein with IPTG induction. b SDS-PAGE analysis of different expression levels of rScFv-Cys in the supernatant and precipitation of bacterial. Lane 1, total bacterial protein without IPTG. Lane 2, total bacterial protein after induction. Lane 3, bacterial supernatant after induction; Lane 4, bacterial precipitation after induction. c SDS-PAGE analysis of rScFv-Cys purification (lane 1, before purification; lane 2, after purification)Back to article page
