TaqMan SNP Assay
From Bridges Lab Protocols
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)
- Postive control(s) (Minor allele) (optional, but recommended)
Protocol
- Dilute gDNA samples to 20ng/ul approx.
- Place gDNA, TaqMan® Genotyping Master Mix (40X), TaqMan® Genotyping Assay (2X) on ice.
- Make up Reaction Master mix (TaqMan® Genotyping Master Mix (40X), TaqMan® Genotyping Assay (2X): see table below).
- Add Reaction Mix (5.25 ul) added to each well (Table 1.)
- Diluted gDNA samples each added to a single well (Table 1.)
