For researchers who use complex genetically modified mouse models, genotyping is the most tedious and time-consuming process and has zero error tolerance. Our Mouse Genotyping Core (MGC) provides fast, accurate, and convenient genotyping service to the mouse research community at affordable prices. Our service is based on conventional PCR and gel electrophoresis methods; by pooling samples from a group of users, we may achieve both technical and cost efficiency through our streamlined operation and quality control.
