Fig. 3From: Detection and monitoring of hypermethylated RASSF1A in serum from patients with metastatic breast cancerCorrelation of the Ct values and logarithmic DNA amplicons. DNA was diluted sequentially tenfold and PCR amplified with primer no. 50. Each measurement was performed as triplicates (mean ± SD). Ct (cycle threshold) is defined as the number of cycles required for the fluorescent signal to cross the thresholdBack to article page
