The Good
Reliable genotyping results for well-established mouse lines
The Bad
Unreliable for genotyping of mouse lines that aren't well-established
The Bottom Line
If you want quick turn around for genotyping, this is a good company to utilize. I would proceed with caution if you want to establish a genotyping assay with them for new mouse lines, especially if your mouse line has a single base pair mutation or any other subtle genetic variation that would make it more difficult to design a reliable TaqMan PCR assay.
