Hi Rob, Here are the protocols from the SNP paper and Michael's modifications for the Spiking paper. I THINK that the reference to LCGreen I again there is a typo, I've emailed him to confirm. I thought that it is because of the difference between SNP curves and Spike curves possibly due to use of LCGreenPlus/3 is why we are doing this. Thanks - I'm looking forward to it. The primers and amplicons are still the same as in the SNP paper so perhaps we do still have them? Bob SNP paper Amplicon CCAGCTGTTCGTGTTCTATGATCATGAGTGTCGCCGTGTG 40 bp (same amplicon/primers) C-G at 21 PCR for the prothrombin, factor V, MTHFR and HFE targets was performed in a LightCycler with reagents commonly used in clinical laboratories. Ten microliter reaction mixtures consisted of 10-50 ng of genomic DNA, 3 mM MgCl2, 1x LightCycler FastStart DNA Master Hybridization Probes master mix, 1x LCGreen I, 0.5 M forward and reverse primers and 0.01U/ l Escherichia coli (E. coli) uracil N-glycosylase (UNG, Roche). The PCR was initiated with a 10 min hold at 50 C for contamination control by UNG and a 10 min hold at 95 C for activation of the polymerase. Rapid thermal cycling was performed between 85 C and the annealing temperature at a programmed transition rate of 20 C/s Primers: From online supplement: Table 1 HFE 187C>G CCAGCTGTTCGTGTTCTATGAT CACACGGCGACTCTCAT Amplicon length (40bp) TM 63oC No of Cycles (35) ------------------------------------------------------------------- Spiking Paper: For high-resolution melting analysis, we used small amplicon melting with primers as close to the SNP as dimer and misprime constraints permit, as described in Liew et al. (2004) [1]. The PCR protocol followed here was modified slightly from the protocol described in [1]. The amplicon was 40bp long. PCR was performed in a LightCycler with reagents commonly used in clinical laboratories. Ten microliter reaction mixtures consisted of 25ng of genomic DNA, 3 mM MgCl2, 1x LightCycler FastStart DNA Master Hybridization Probes master mix, 1x LCGreen I, 0.5 $\mu$M forward (CCAGCTGTTCGTGTTCTATGAT ) and reverse (CACACGGCGACTCTCAT) primers and 0.01U/$\mu$l Escherichia coli (E. coli) uracil N-glycosylase (UNG, Roche). The PCR was initiated with a 10 min hold at 50\degrees C for contamination control by UNG and a 10 min hold at 95\degrees C for activation of the polymerase. Rapid thermal cycling was performed between 85\degrees C and the annealing temperature at a programmed transition rate of 20\degrees C/s for 40 cycles. Samples were then rapidly heated to 94\degrees C and cooled to 40\degrees C followed by melting curve analysis between 60\degrees C and 85\degrees C to confirm the presence of amplicon. Prior to analysis on the HR1, samples were again rapidly heated to 94\degrees C and cooled to 40\degrees C to promote heteroduplex formation.
