Germline Transmission:  Earliest citation of germline transmission: J:152376
Parent Cell Line:  RW-4 (ES Cell)
Strain of Origin:  129X1/SvJ
Allele Type:    Targeted
Mutation:    Insertion
Mutation detailsThe targeting vector was designed (by site-directed mutagenesis) to change the alanine-guanine to guanine-alanine at basepair 1964-65 of murine IL-4Ra cDNA, corresponding to a single amino acid substitution of glutamine to arginine at codon 576 (Q576R). This also inserted a loxp-flanked PGK-neo cassette within intron 11. The construct was electroporated into 129X1/SvJ-derived RW4 embryonic stem (ES) cells. Correctly targeted ES cells were transiently transfected with a Cre-expressing vector to remove the selection cassette (leaving a single loxp site in intron 11) and then injected into C57BL/6 blastocysts.
