However, another possibility is that the differences in the numberof colonies on the plates are simply due to differencesin the ability of the petri plates to support the growthof colonies. For example, perhaps the selective agentor the nutrients in the media were not evenly distributed in the molten agar poured into the petri dishes.What experiment could you do to determine whetheror not differences in the petri plates were a factor inthe experiment?Bradford Assay Fill in the average A595 and A595 of sample minus A595 of blank.
