BRC No. | RBRC03730 |
Type | Targeted Mutation![]() |
Species | Mus musculus |
Strain name | B6;129S4-Dnmt3a<tm1Enl> |
Former Common name | Dnmt3a<tm1Enl>; Dnmt3a null KO |
H-2 Haplotype | |
ES Cell line | J1 [129S4/SvJae] |
Background strain | |
Appearance | |
Strain development | Developed by Masaki Okano and En Li, Massachusetts General Hospital in 1999. J1 ES cells were used to generate the mutant mice. The mutant mice were crossed to C57BL/6. |
Strain description | Dnmt3a knockout mice. A 0.3 kb region containing exons of Dnmt3a encoding PC and ENV motif was replaced with an IRES-beta-geo cassette. Homozygous mutant mice appear normal at birth, but most mutant mice become runted and die at about 4 week of age. Dnmt3a floxed mice (RBRC03731), Dnmt3b knockout mice (RBRC03732), Dnmt3b floxed mice (RBRC03733). |
Colony maintenance | Heterozygote x Wild-type [C57BL/6JJcl] |
