Dear sir
We are working on protein toxins.These toxins come under A-B model of toxins.Both A and B moieties when endocytosed by their respective cells (J774A.1,RAW264.7)cause cytolysis .While doing tissue culture assays we have found that our cell line has developed some kind of resistance to these toxins and all the cells remain viable even after prolonged incubation.If you have some suggestions please help us.
                                                                                                                                             Thanks
                                                                                                                                           Aparna
