title: A Quick, No Frills Approach to Mouse Genotyping.
abstract: Mice are extremely powerful mammalian genetic model organisms for basic and medical research, but managing a colony of transgenic mice is time consuming and expensive, many times requiring the help of dedicated technicians. Slow and laborious genotyping procedures add to the hassle. Outsourcing is costly and may not be as fast as desired, especially when setting up time sensitive experiments. Ultrafast genotyping protocols often require real-time PCR instruments and commercial reagents that may not be economical or practical. This protocol, adapted from methods suggested by The Jackson Laboratory, employs a minimalist approach that maximizes convenience by simplifying the tissue digestion/DNA extraction process and using a high-speed electrophoresis system for sample analysis. Genotype PCR results can be obtained in 3 h or less for as many samples as can fit in a PCR machine or can be efficiently handled by a user. Subsequent ethanol or chloroform purified DNA can be used in a standard PCR reaction to roughly identify a homozygous and a hemizygous mouse.
