Protocol 31877: Separated PCR Assay - Tg(LRRK2*G2019S)2AMjff-Chr2
Version 1.0

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 = 224 bp
Heterozygote = 165 bp and 224 bp
Wild type = 165 bp

This assay may be capable of distinguishing hemi from hom.  Transgene insertion site is known to be on mouse Chr 2.

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 transgene copy number evaluation.  If this is required, it is suggested to type by qPCR.

Cycling

Step Temp °C Time Note
1 94.0 --
2 94.0 --
3 65.0 -- -0.5 C per cycle decrease
4 68.0 --
5 -- repeat steps 2-4 for 10 cycles (Touchdown)
6 94.0 --
7 60.0 --
8 72.0 --
9 -- repeat steps 6-8 for 28 cycles
10 72.0 --
11 10.0 -- hold
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.
