Protocol 30377: Standard PCR Assay - Tg(C9ORF72*)1Rhbr Alternate1
Version 1.0

Notes

This assay will NOT distinguish hemizygous from homozygous transgenic animals.

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.

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

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.
