Allele : Gt(ROSA)26Sor<em25(KRT18-ACE2)Mvw> gene trap ROSA 26, Philippe Soriano; endonuclease-mediated mutation 25, Michael V Wiles

Primary Identifier  MGI:6877060 Allele Type  Endonuclease-mediated
Attribute String  Epitope tag, Humanized sequence, Inserted expressed sequence Gene  Gt(ROSA)26Sor
Strain of Origin  C57BL/6J Is Recombinase  false
Is Wild Type  false
molecularNote  CRISPR/cas9 genome editing and RMCE (recombinase-mediated cassette exchange) are utilized to insert a human keratin 18 promoter directing expression of human ACE2 followed a C-terminal FLAG epitope tag into a modified Gt(ROSA)26Sor (B6.RosaBxb-GT/GA) locus. The C57BL/6J-derived zygotes carrying the Gt(ROSA)26Sor (RosaBxb-GT/GA) allele were previously targeted to insert a dual Bxb1 attP-site "safe harbor landing pad" in the first intron of Gt(ROSA)26Sor. The landing pad contains a 48 bp Bxb1 attP-GT sequence and a 48 bp Bxb1 attP-GA sequence separated by a 240 bp spacer of native Gt(ROSA)26Sor sequence. The DNA donor plasmid, carrying two heterologous attB sites and donor transgene, was then microinjected with Bxb1 integrase into the RMCE-ready zygotes (attP-GT/GA).
