一般描述

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。

外形

形式：纯化

分析说明

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）。 10⁶ 单位相当于大约 10 μg 的纯蛋白质，足以处理 1L 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

制备说明

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。

储存及稳定性

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。
