Related Genes
GFP fluorescent protein
Species
Sprague Dawley
Appearance
White
Genotypes
GFP cKI (wt/mut)
Development
A designed targeting sequence containing pCAG-loxP-3*STOP-loxP- 3*GFP-WPRE-bGHpA was inserted to the Rosa26 between exon 1 and exon 2 using CRISPR/Cas9 technology. This strain was maintained on a Sprague Dawley genetic background.
Description
These GFP cK I rats knockin rats have a floxed-STOP cassette preventing expression of the downstream bicistronic sequence (3*GFP). Although under control of a CAG promoter, widespread expression of GFP is prevented by the STOP cassette. After exposure to Cre recombinase, expression of GFP will be observed.
