This assay cannot distinguish between homozygous and heterozygous mutant mice except for Sod1tm1Leb mutation.
This assay does not work well without the use of a Hotstart (We are using Taq Start Antibody mixed 1:1 with Taq polymerase).
Use Perfect Match© (Stratagene) added before Taq to delete non-specific bands.
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.
Homozygote or Heterozygote = 240 bp and 123 bp
Internal positive control (Sod1) = 123 bp
Separated by gel electrophoresis on a 1.5% agarose gel.
