Genotype No Data  
Strain development Developed by Masaki Okano and En Li, Massachusetts General Hospital in 2001. J1 ES cells were used to generate the mutant mice. The mutant mice were crossed to C57BL/6.  
Strain description Dnmt3b floxed mice. Exon 19 of the Enmt3b was flanked by loxP sites. Conditional Dnmt3a deficient mice can be generated by crossing with tissue-specific Cre mice. Homozygous mice are viable and fertile. Dnmt3a knockout mice (RBRC03730), Dnmt3a floxed mice (RBRC03731), Dnmt3b knockout mice (RBRC03732).  
Colony maintenance Homozygote x Homozygote [or Crossing to C57BL/6JJcl]
