For this purpose we used the Cancer and Normal TissueScanTM Cancer Survey cDNA qPCR Array – I (CSRT501) (Origene) which contains tissue cDNAs that are synthesized from high quality total RNAs of pathologist-verified tissues, normalized and validated with β-actin in two sequential qPCR analyses, and are provided with clinical information and QC data. The gene discussed is ACTB; the disease is cancer.
