      DescriptionEF5 Hypoxia Detection Kit, Alexa Fluor® 488
      Background InformationA number of imaging markers which target hypoxia exist and are widely used in research. EF5 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 Alexa Fluor® 488 is then used to selectively bind the EF5 adducts.

      Advantages of the EF5 Hypoxia Detection Kit:
      • 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 binding images can be calibrated to provide quantitative data on the pO2 values of each cell (Koch CJ, 2002):
      The fluorescent images obtained from EF5 binding can be calibrated according to camera settings and a “cube-binding” value which is obtained through a separate procedure. The intensity values of calibrated images are directly related to actual tissue pO2 values. As a result, these images provide information regarding not only where hypoxic areas may or may not be, but also data regarding the distribution and levels of hypoxia.
