R2G2模型是一种具有超免疫缺陷表型的双基因敲除小鼠。模型是通过回交IL2RG公司(普通伽玛链)对混合背景小鼠(C57BL/6和129混合)的突变Rag2. The recombination activating gene 2 (Rag2) interruption causes a deficiency in T and B cells. The Common gamma chain gene (IL2RG公司) interruption results in a lack of functional receptors for IL-2, IL-4, IL-7, IL-9 and IL-15.
Envigo acquired from Fox Chase Cancer Center in 2016, where the model had been maintained since 2005. The model is a white-bellied, light chinchilla (light tan).

Envigo uses well-established techniques to successfully produce time mated rats, mice, hamsters, and rabbits. We use an Impedence Meter for determining the stage of estrus in rats prior to breeding. Time mated rats and mice are determined by observation of a vaginal plug. Plug date is considered to be day zero (0) of gestation.
由于怀孕时间的自然变化,不能保证确切的分娩日期。此外,Envigo不能保证每窝产仔的最小数量。B0B体育平台下载
