Germline Transmission:  Earliest citation of germline transmission: J:167922
Parent Cell Line:  Bruce 4 (ES Cell)
Strain of Origin:  B6.Cg-Thy1a
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsThe 295 bp of the pre-microRNA was replaced with a floxed neo cassette. Cre-mediated recombination removed the neo cassette. The absence of transcript expression was confirmed by qRT-PCR on bone marrow, spleen, and thymus extracts. (J:173671)
