Protocol 22585: Standard PCR Assay - Tg(GFAP-cre)25Mes
Version 1.3

Notes

Primers oIMR1900 and oIMR1901 together amplify an artifact band of ~700bp in wild type mice, that is not amplified in the transgenic mice, presumably due to competition.

Primer oIMR1900 is two nucleotides shorter (at 3' end) than the primer sequence provided in the original reference.

This assay will NOT distinguish hemizygous from homozygous transgenic animals.
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

Transgene = 190 bp
Internal positive control = 700 bp
Separated by gel electrophoresis on a 1.5% agarose gel.

JAX uses a very high speed Taq (~1000 bp/sec), use cycling times recommended for your reagents.
JAX uses a 'touchdown' cycling protocol and therefore has not calculated the optimal annealing temperature for each set of primers.
