Protocol 35662: Probe Assay - Cdh12<em1(IMPC)J>
Version 1.0

Notes

Taqman qPCR protocols are run on a real time PCR instrument. Use an appropriate instrument specific Fluorophore/Quencher combination.

 

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.

This allele was generated at The Jackson Laboratory by electroporating Cas9 protein and 2 guide sequences AGGGATAGACAAGATGGCTG and ATCATTGATTGAATAATATA, which resulted in a 665 bp deletion beginning at Chromosome 15 position 21,358,579 bp and ending after 21,359,243 bp (GRCm38/mm10). This mutation deletes ENSMUSE00000340213 (exon 3) and 370 bp of flanking intronic sequence including the splice acceptor and donor and is predicted to cause a change of amino acid sequence after residue 77 and early truncation 6 amino acids later.
