Protocol 42384: Standard PCR Assay - Tn(pb-CAG-cas9*,-EGFP)1Yangh-Chr14 Alt 1
Version 2.0

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

>chr14:66852051+66852399 349bp AGACAGGGGACTGGACAGAA GCTCCGACATTGTGCAGATA

Mutant = 510 bp
Heterozygote = 510 bp and 349 bp
Wild type = 349 bp

This assay is capable of distinguishing hemi from hom.  Transgene insertion site is known to be on mouse Chr 14.

This assay is designed around this insertion site, but it has not been tested on hom animals.

This assay is NOT able to be used for copy number evaluation.  If this is required, it is suggested to type by qPCR.

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.
