Enzyme delivered in smaller package protects cells from radiation damage

...ter irradiation, the cells were plated in a growth medium and incubated at body temperature for 7 days at which time colonies of greater than 50 cells were counted. The MnSOD transfected cells were significantly more resistant to ionizing radiation than the non-tranfected cells. However, there was no si...
