Protocol 28173: Standard PCR Assay - Foxp3<tm9(EGFP/cre/ERT2)Ayr>Alternate2
Version 2.2
Notes
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 = 396bp
Heterozygote = 322 bp and 396 bp
Wild type = 322 bp
X-linked mutation

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.
