Biochem/physiol Actions
DNA alkylating agent that is carcinogenic in many animal species. Although it can induce benign and malignant tumors in most organs, MNU is most often used to model mammary tumor initiation and progression.
Caution
Injecting any compatible solvent directly into the vial permits preparation of any desired strength solution without exposure.
包装
