Protocol 25105: Separated MCA Assay - Csf2/Il3<tm1.1(CSF2,IL3)Flv>
Version 2.2

Notes

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


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 = 189 bp
Heterozygote = 189 bp and 207 bp
Wild type = 207 bp

MgCl2 2.60 mM
dNTPS-kapa 0.26 mM
11921 0.50 uM

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)

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.
