Protocol 29438: Standard PCR Assay - Dnmt1<tm3Jae>
Version 4.2

Notes

Melting curve analysis is done using a Roche Light Cycler 480.
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 Tm = 91.2°C
Wild type Tm = 84.8°C
Separated by gel electrophoresis on a 1.5% agarose gel.

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 --

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.
