Description: Pimonidazole accumulates in hypoxic cells via covalent binding with macromolecules or by forming reductive metabolites after the reduction of its nitro group. It can be used for qualitative and quantitative assessment of tumor hypoxia. Pimonidazole is a novel hypoxia marker for the complementary study...

Hypoxic cells are low oxygen cells that when present in tumors are radioresistant and chemoresistant. Pimonidazole is a small molecule radiosensitizer that has proven to be an effective and nontoxic hypoxia marker for human squamous cell carcinomas of the cervix, head, and neck. This immunochemical hypoxia marker...
