Strain descriptionB6.129S1-Tnf<tm1Ljo>/Rbrc. TNF, tumor necrosis factor is a multifunction proinflammatory cytokine, play a critical role in regulating of the development and function of the immune system. Homozygous mutant mice show no cytotoxicity of TNF.
Colony maintenanceHomozygote x HomozygoteHomozygous mutant mice show a normal development and no gross morphological abnormalities.
