Using Real-Time PCR to Determine Blood Type. Lightcycler data. Example: Blood Type SNPs. Use two assays in a lightcycler: B assay (which detects the SNP at 796) O assay (which detects the SNP at 261). Blood Typing. B Assay. O Assay. "O" (deletion). "not-O" (G). " "not-B" (C). "B"

Example: Blood Type SNPs • Use two assays in a lightcycler: • B assay (which detects the SNP at 796) • O assay (which detects the SNP at 261).

Group Practice: What’s this person’s blood type? B Assay O assay "O" (deletion) "not-O" (G) ""not-B" (C) "B" (A) fluorescence fluorescence Type BO 55 65 55 62
What is the blood type? "O" (deletion) "not-O" (G) ""not-B" (C) "B" (A) fluorescence fluorescence Type AO 55 65 55 62
