Figure 1. SNaPshot analysis of rs2229992 SNP as a quantitative test.

Figure 1

Regression analysis of the amplification products of two homozygous control cDNAs mixed in different proportions and analyzed in triplicate by SNaPshot. Allele frequencies were calculated by the peak heights: freq. C = C/(C+kT), where the correction factor k is determined from the mix simulating an actual allele frequency of 0.5 (5:5). Measured allele frequencies were plotted against the expected values. A near-linear relationship was observed across all data points (R2 = 0.9983).
