Protocol 24884: Separated MCA Assay - Tg(Thy1-TARDBP)4Singh
Version 2.2

Notes

Donating Investigator reports this transgene had integrated at locus 6qB3 of the mouse genome (nucleotide 56,524,796) and did not interrupt any known gene.

WT F and Common R primers amplify a PCR product from mouse of 303 bp.  Tg F primer is specific for the Tg.

This assay will distinguish hemizygous from homozygous transgenic animals.

Changed common from .13791 (no amplification with Tg)  to .13790 per Kai (successful amplification with Tg)  SC 3-1-12.

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 = ~500 bp
Heterozygote = 303 bp and ~500 bp
Wild type = 303 bp

Melt Peaks
Wt = 82.7°C +/- 1
Tg = 82.6

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.
