Description générale

A number of imaging markers which target hypoxia exist and are widely used in research. EF5 (2-(2-Nitro-1H-imidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl) acetamide) is a compound developed at the University of Pennsylvania by Dr. Cameron Koch and Dr. Sydney Evans. Upon injection into animal tissues, EF5 selectively binds to hypoxic cells and forms adducts. A mouse monoclonal antibody, clone ELK3-51 which is directly conjugated to either Cyanine 3 or Alexa Fluor™ 488 is then used to selectively bind the EF5 adducts.

Advantages of the EF5 Hypoxia Detection:
• EF5 exists in only one form:
Pimidozole, an alternative hypoxia marker, exists in two forms; one of which is charged and very hydrophilic, the other lipophilic. Pimidozole thus has a very complex biodistribution. In contrast, EF5 is lipophilic and uncharged and this allows very rapid and even tissue distribution.

EF5 is a 2-nitroimidazole-based hypoxia marker that selectively binds hypoxic cells.
