Protocol 22761: Standard PCR Assay - Smn1<tm1Msd>
Version 2.3
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 = 500 bp
Heterozygote = 500 bp and 800 bp
Wild type = 800 bp
Two public protocols are supplied- different band sizes.
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.
