| Platform Stocks of Immunodeficient Mice | Common Abbreviation | Characteristics |
| NOD.Cg-PrkdcscidIl2rgtm1Wjl | NSG | The Il2rg targeted mutation is a complete null, is not expressed and will not bind cytokines |
| NOD.cg-PrkdcscidIl2rgtm1Sug | NOG | The Il2rg chain lacks the intracytoplasmic domain. It Is expressed and will bind cytokines but will not signal |
| C;129S4- Rag2tm1.1Flv | BRG | On a mixed BALB/c x 129 Rag2null strain. Il2rg is complete null, is not expressed and will not bind cytokines |
