Resulting smears of amplifications of blastocyst DNA from the three protocols. A) Resulting smears of amplifications from Me-RDA and HMe-RDA methodologies. One round (R1) of kinetic enrichment results in a HpaII site-enriched smear (H) and a BfaI site-enriched smear (B) with PCR control for HpaII (T-H) and PCR control for BfaI (T-B). L: 100 pb ladder. B) Resulting smears from HELP Cocktail methodology. TasI ligation mediated-PCR (PCR1). Final PCR (PCR2).
