Genotype a/a B/B C/C  
Strain development Developed by Drs. Kohki Kawane and Shigekazu Nagata at Osaka University in 2001. A neomycin cassette replaced exons 1-5 and part of 6 of the Dnase2a gene. The mutant mice were backcrossed to C57BL/6.  
Strain description B6;129-Dnase2a<tm1Osa>. In macrophage, DNase II, deoxyribonuclease II is responsible for digesting nuclear DNA expelled from erythroid precuursor cells. Homozygous null mice for DNase II are embryonic lethal due to sever anemia, and impaired definitive erythropoiesis in the fetal liver. This strain is useful for elucidation of the function of DNase II gene.  
Colony maintenance Backcross to C57BL/6 (Heterozygote x C57BL/6NCrlCrlj)
