Protocol 22214: QPCR Assay - Trisomy QPCR
Version 4.0

Notes

Taqman qPCR protocols are run on an ABI 7500, 7700, 7900 or the Roche LightCycler
480. 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.
