Affect of affinity purified proteins on bacterial growth. a. Purification of OsGR-RBP4, OsGR-RBP4PΔC and OsFKBP20 proteins by affinity column chromatography. Arrows indicate the presence of partially purified proteins in respective panels. Pre-stained markers are shown on the extreme left panel. b. Effect of purified OsGR-RBP4, OsGR-RBP4PΔC and OsFKBP20 proteins on the survival of E. coli M15 cells under in vitro conditions. Photograph shows serial dilutions made after 8 h and spotted on LB agar plates with antibiotic selection.
