Figure 1From: Differential gene expression profiles are dependent upon method of peripheral blood collection and RNA isolationDifferences in RNA quality and yield between PAXgene™ and Tempus™. The tempus system has higher mean yields, improved RNA purity based on OD 260/230 ratios, less degradation based on GAPDH 3'/5 ratios, and a higher number of expressed transcripts based on Percent Present Calls.Back to article page
