Notes
Taqman qPCR protocols are run on a real time PCR instrument. Use an appropriate instrument specific Fluorophore/Quencher combination. The transgene genotype is determined by comparing ΔCt values of each unknown sample against known homozygous and hemizygous controls, using appropriate endogenous references.
The genotyping protocol(s) presented here have been optimized for reagents and conditions used by The Jackson Laboratory (JAX).
To genotype animals, JAX recommends researchers validate the assay independently upon receipt of animals into their facility.
Reaction cycling temperature and times may require additional optimization based on the specific genotyping reagents used.
Expected Results
Mutant= 120 bp
Wild Type = 122 bp
