C57BL/6, often referred to as "C57 black 6", "B6", "C57" or "black 6", is a common inbred strain of laboratory mouse. It is the most widely used "genetic background" for genetically modified mice for use as models of human disease.

C57BL/6J is the most widely used inbred strain and the first to have its genome sequenced. C57BL/6J mice are resistant to audiogenic seizures, have a relatively low bone density, and develop age related hearing loss. They are also susceptible to diet-induced obesity, type 2 diabetes, and atherosclerosis.

C57BL/6 mice are the most used inbred strain in research. Our C57BL/6 mouse colonies are genetically identical within each strain, making them free of genetic differences that could impact research results.

C57BL/6， 常被称作“C57 black 6”、“C57”或者“black 6”（标准简称为B6）, 是一种常见的近交品系实验鼠。 在 遗传学 试验中广泛用作 转基因鼠 以模拟人类的基因缺陷类疾病。 因其可用作 同类系 、易于繁殖和体格健壮等特性，是使用范围最广、销量最好的一支鼠株品种。 1921年C.C.Little用Abby Lathrop 小鼠 近亲培育数个近交系，使编号为57的雄鼠与52号雌鼠交配，培育成C57。 其中毛色固定为黑色的培育成C57BL，BL是英文 Black （黑色）的缩写。 1937年，Little将维持 …

For over a century, the Jackson Laboratory has raised and distributed countless C57BL/6J (000664) mice. But has anyone wondered why this particular mouse, first bred in 1921 by Jackson Laboratory founder C.C. Little, has been so popular or acquired its name?

在肿瘤学、生理学、免疫学和遗传学研究中，C57BL/6J小鼠被广泛使用，尤其是在糖尿病、肥胖症、动脉粥样硬化等研究中更是不可或缺。 它们还被用于研究人类基因高度相似的一些疾病，如阿尔兹海默症、老年抑郁症、骨关节炎等。 一、来源. 1921年，C.C.Little用Abby Lathrop小鼠近亲交配。 其中雌鼠57号与雄鼠52号交配为最初的交配对，所培育出的后代被标记为C57。 C57小鼠的毛色固定为巧克力色者称为C57BR；将毛色呈黑色的进行固定，黑色英文Black缩写为BL，所以将 …

Charles River uses our International Genetic Standardization (IGS) program coupled with a pyramid mating system designed to maintain authenticity and the highest possible levels of genetic uniformity.

The Class C57 (C57形) is a type of 4-6-2 steam locomotive built in Japan from 1937 to 1947. A total of 201 Class C57 locomotives were built and designed by Hideo Shima . [ 1 ] [ 2 ] Another 14 Class C57 locomotives were built for export to Taiwan in 1942 and 1953.

1957年12月9日，CT271牽引北上22次 普通車，在行經 縱貫線 桃園 與 鶯歌 間發生 脫軌 翻覆事故，事故起因為孩童於路線上嬉戲並於軌道上推疊 道碴 所引起，此事故造成18人死亡（含 司機員），116人輕重傷。 後來臺鐵將CT271修復並繼續使用至停用為止。 目前有四部CT270型留下來，車號及其保存狀況分述如下： 1983年2月停用後存放於嘉義扇形車庫中，1991年嘉義扇形車庫拆除， 基隆市政府 便向臺鐵申請保存CT271，並於同年6月迴送到 基隆車站 後移往 情人湖 公 …
