Anabaena PCC7120 infection with Cyanophage A1

In order to examine the response of Anabaena sp. PCC 7120 to an infection of the Cyanophage A1, we have used customized microarrays to identify genes potentially up- or downregulated by the infection. For this we compared cell culture before and after infection. The Anabaena sp. PCC 7120 cultures incubated under optimal conditions before split into two cultures of the same size. One culture was infected with a MOI of 2 and both cultures incubated further by 30 centigrade for one hour. Afterwards, the cells were harvested. This experiment was repeated in order to receive replicates.
