In this module you will measure genomic instability using two techniques: the CometChip and immunofluorescence. Your first task is to critically think through the development of the CometChip assay and determine which conditions provide the best results for loading mammalian cells into the device. To this end, you will consider variables that affect cell loading into the microwells of the CometChip. The data you collect will be used to determine the conditions for subsequent assays.
Next, you will use the CometChip assay to measure DNA damage in response to chemical treatments and to assess repair capacity across different cell lines. Specifically, you will study the effect of oxidative stress in these experiments. Last, you will examine the effect of chemical treatment on the abundance of double-strand breaks using an immunofluorescence approach.
