近交系杂交

MATERIALS: The donor mice were the male F1 hybridism mice of cleaning inbred strain C57BL/6 and BALB/c mice or the cleaning C57BL/6 mice. The recipient was the cleaning female inbred strain BALB/c mice. These mice were used for establishing leukemia models.

材料：供鼠为清洁级近交系C57BL/6小鼠和C57BL/6小鼠与BALB/c 小鼠杂交的雄性F1小鼠，受鼠为清洁级近交系雌性BALB/c小鼠，用于构建白血病小鼠模型。

Therefore the method of PCR-analyzed microsatellites can be used for distinguishing between inbred and outbred, different strains, strain and substrain.

说明该方法能有效地对近交系与杂交系、品系与品系、品系与亚系加以区分。
