Analysis Note

比活度：ESGRO® 补充剂在小鼠胚胎干细胞（D3 & MBL-1）和鼠 M1 髓样白血病细胞上进行了评估（4）。50 单位的标准定义为在 1.0mL 组织培养基中可诱导 50％ 的 M1 菌落分化的 ESGRO 补充剂的浓度（4）。 10E7 单位相当于大约 100 μg 的纯蛋白质，足以处理 10L 的 ES 细胞培养基。

胚胎干细胞测定：分化抑制测定，浓度为 1000 单位/mL 小鼠骨髓白血病细胞 M1：比活度 >/= 108 单位/mg

Application

ESGRO 补充剂的应用包括用作体外维持鼠 ES 细胞多能表型的试剂。

建议的实验方案：

ES 细胞：在 D3 和 MBL-1 多能 ES 细胞培养物中，研究发现，通常每 1.0 mL 组织培养基需要 1000 U ESGRO 补充剂来维持具有干细胞表型的 ES 细胞。 相似浓度的 mLIF 也已用于遗传修饰的 ES 细胞的种系传递（E3）。

在推荐浓度下，107 单位的 ESGRO 足以用于 10.0 L 的组织培养基，而 106 单位的 ESGRO 补充剂足以用于 1.0 L 的组织培养基。

General description

ESGRO 小鼠 LIF 培养基补充剂以有效单位/mL 的形式提供，以确保批次之间的性能一致。 每批 ESGRO 补充剂均经过严格的质量控制测试，以确保能可靠地抑制小鼠多能干细胞分化。 ESGRO 小鼠 LIF 补充剂可用于小鼠胚胎干（ES）和诱导性多能干（iPS）细胞的基于饲养层和无饲养层的培养。
小鼠白血病抑制因子（LIF，mLIF）通过抑制自发分化，促进多能小鼠胚胎干（ES）和诱导多能干（iPS）细胞的自我更新和长期维持。

Physical form

ESGRO 补充剂以液体形式提供，含量为 107 单位，溶于 1.0 mL 磷酸盐缓冲盐水，含 1％w/v 牛血清白蛋白 BSA 为载体以确保稳定性。
形式：纯化

Preparation Note

ESGRO 补充剂在环境温度下运输。出于客户关系，可能包含一个冰袋，但确实没必要。开发期间已使用 ESGRO 补充剂进行了广泛的稳定性测试。 该产品自生产之日起，以浓缩形式或在无菌组织培养基中稀释后至少可稳定保存 18 个月，且对 ES 细胞没有活性损失。 若要长期储存，建议将 ESGRO 补充剂储存于 4°C。 冻融会降低效力。建议在使用前，将 ESGRO 补充剂在无菌组织培养基中稀释并等分至合适的浓度，然后储存于 4°C。应避免冻融。在 ES 细胞培养期间，该产品在 37°C，5％ CO2 培养箱中可稳定至少 7 天。
提供的 ESGRO® 补充剂经 0.22 微米无菌过滤，并在支原体检测中呈阴性。
