Protocol 22205: QPCR Assay - Tg(tTA)
Version 10.0


Taqman qPCR protocols are run on an ABI 7500, 7700, 7900 or the Roche LightCycler 480. Use an appropriate instrument-specific Fuorophore/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.

Primer 9344 replaced with 13639, 3' Iowa Black with Zen

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.
