| molecularNote | The bicistronic Rxfp1-P2A-Cre knock-in allele was created using homologous recombination (aided by targeted CRISPR/cas9 endonuclease activity) to insert a viral 2A oligopeptide sequence (T2A; mediates ribosomal skipping) and a Cre recombinase gene (cre) the gene. The targeting vector, Cas9 endonuclease, and guide-RNA were mixed and injected into the v6.5 mouse embryonic stem cells. Colonies grown from transfected cells were directly screened for successful integration and were aggregated with albino morula and implanted into pseudopregnant females, which produced germ-line-competent chimeric founders. The ampicillin cassette is still present in this allele. |
