Protocol 20740: Standard PCR Assay - Il4ra<tm1Sz>
Version 4.0

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 = 247bp
Heterozygote = 247 bp and 441 bp
Wild type = 441 bp
Separated by gel electrophoresis on a 1.5% agarose gel.
