I have used qPCR arrays to test the expression of 48b genes in two groups of cells. These arrays showed 10 genes which their expressions are significantly different between the groups. The next step is to test the protein expression of these genes using western blotting assays. I wonder here, do I have to test the expression of these genes individually in both groups using specific PCR assays?. If anybody has used these arrays or similar arrays please let me know your experience
