Figure 4From: Characterisation of the Binding Properties of Bacillus Thuringiensis 18 Toxin on Leukaemic CellsHeterologous competitive binding assays- biotinylated purified Bt 18 toxin versus various anticancer drugs. Fixed concentration (7.41 nM) of biotinylated purified Bt 18 toxin was allowed to compete with various concentrations (0 nM to 59.26 nM) of cisplatin, doxorubicin, etoposide, methotrexate and navelbine, separately for 1 hour at 37°C.Back to article page
