Genotype identification of Math1/LacZ knockout mice based on real-time PCR with SYBR Green I dye.

Knockout mice are widely used in all fields of biomedical research. Determining the genotype of every newborn mouse is a tedious task, usually performed by Southern blot hybridization or Polymerase Chain Reaction (PCR). We describe here a quick and simple genotype identification assay based on real-time PCR and SYBR Green I dye, without using fluorescent primers.
