Materials
- TaqMan® Genotyping Assay (supplied at 20X, 40X or 80X) (Applied Biosystems).
- TaqMan® Genotyping Master Mix (supplied at 2X)(Applied Biosystems).
- StepOnePlus Real-Time PCR System (Applied Biosystems).
- PC/Laptop with StepOnePlus Software installed.
- MicroAmp Fast 96-Well Plates.
- Optical Plate Covers.
- Nuclease-Free Water
- Sample Genomic DNA (extracted as described in Blood DNA Extraction)
