Protocol 27288: Standard PCR Assay - Spp1<tm1Blh>
Version 6.2
Notes
This assay does not work well without the use of a Hotstart Taq polymerase.
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 = 181 bp
Heterozygote = 181 bp and 387 bp
Wild type = 387 bp
Heterozygote = 181 bp and 387 bp
Wild type = 387 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.
