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.
Genotyping by PCR is performed to determine the absence or presence of the transgene. This strain has some variability in repeat size, therefore Southern blotting is performed to accurately determine the size, in kilobases, of the repeat within the transgene.
Tg= 150 bp
