Homologous competitive binding assays. The unlabelled toxin and biotinylated purified Bt 18 toxin were allowed to compete for binding site on A) CEM-SS, B) CCRF-SB, C) CCRF-HSB-2 and D) MCF-7 separately using fixed concentration (7.41 nM) of biotinylated purified Bt 18 toxin and various concentrations (0 nM to 59.26 nM) of the unlabelled toxin for 1 hour at 37°C.
