ABSTRACT:
The cytotoxicity of DNA reactive cross-linking agents can be modified or reversed by exposing cells exposed to such agents to specific endocytotically absorbed materials. These materials should be capable of interfering with the cross-linking of the DNA. For example, electrophillic materials such as serum proteins, are useful for this purpose.
