Genotyping is commonly used to define specific gene alterations or the presence of transgenes in mice. This procedure is typically done using DNA isolated from mouse tail tissue. Although there are commercially available kits for tail DNA isolation, they can be time consuming and costly for routine genotyping. In this study, we describe a rapid, "crude" DNA isolation method using mouse tail tissue and compare it to a frequently used, commercially available kit in the genotyping of over 1,000 total mice from 8 genetic lines. Our genotyping results were obtained faster and less expensively but with the same success rate (Crude method: 97. 7 %, Kit method: 98. 4 %). To our knowledge, this is the first systematic study to compare the reliability of this crude DNA isolation method for mouse genotyping compared to a commercially available kit.
