Choice of Stable vs Transient Transgenics

Transgenic mice are typically made as stable lines, which entails breeding founder
mice and evaluating the phenotype in the F1 or F2 generation. Alternatively, F0s may be
analyzed directly. Such a “transient” transgenic approach offers the advantage of relatively
quick results. A disadvantage is that the transgenic line is not maintained; therefore
further analysis of any phenotype will require more injections.
