Protocol 23077: Standard PCR Assay - Generic iCre
Version 1.3

Notes

Transgene = 236 bp
Internal positive control = 324 bp

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

This assay will NOT distinguish hemizygous from homozygous transgenic animals.

This assay does not work well without the use of a Hotstart Taq polymerase.

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.
