Figure 2From: SHOX2 DNA Methylation is a Biomarker for the diagnosis of lung cancer based on bronchial aspirates Analytical assay performance. Analytical performance of the quantitative real time PCR assay for quantifying SHOX2 DNA methylation. Different amounts of methylated DNA (3.1 - 10,000 pg) were spiked into a background of 50,000 pg unmethylated DNA. Number of replicates: Sixteen (0 and 3.1 pg), eight (6.2-200 pg) and three (1,250-10,000), respectively.Back to article page
