The interaction between thiabendazole (TBZ) and calf-thymus DNA (ct-DNA) was studied by experimental and molecular modeling methods. The intrinsic fluorescence of TBZ was quenched in the presence of ct-DNA. In competition experiments. TBZ could displace Hoechst 33258 (a minor groove binder to DNA). https://www.wholisticpet.shop/product-category/novelty-items-games/
