RB-90740 is a type of biological reducing agent. RB-90740 is activated through metabolic reduction and generates cytotoxic products, thereby selectively killing tumor cells (usually in a hypoxic environment). RB-90740 has selective toxicity towards hypoxic cells, which is mainly achieved by causing DNA strand breaks and activating reducing enzymes (such as Cytochrome P450). RB-90740 does not initially exhibit cytotoxicity similar to its in vitro properties in hypoxic cells in mouse models. RB-90740 can be used to study the tumor physiological environment

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
