Protocol 9432: Pyrosequencing Assay - Lass1<to>Pyro
Version 1.0

Notes

This genotyping assay uses pyrosequencing technology and is run on the Biotage PSQ 96MA. The Jackson Laboratory is not posting the complete details of our pyrosequencing genotyping assays as the primers for pyrosequencing cannot be used for sequencing using more traditional methods. The wild type and mutant nucleotides and the flanking DNA sequence are provided below.

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 = A/A
Heterozygote = C/A
Wild type = C/C
