产品名称 ：去外泌体胎牛血清（Exo-FBS）

英文名称 ：Exosome depleted Fetal Bovine Serum

品牌 ：ViVaCell

货号 ：C38010050

规格 ：50 mL/瓶

贮存 ：-20℃

说明 ：该产品仅供科研使用

 

 

 

      胎牛血清（Fetal Bovine Serum, FBS）是大多数细胞培养重要的生长支持物 。天然来源的FBS会含有大量的外泌体（exosome）等囊泡（Extracellular Vesicles）成分 。由于FBS来源的外泌体会对研究结果产生巨大干扰 ，因此 ，外泌体研究时必须使用去除外泌体后的FBS进行细胞培养 。

|   产品特点

1. 专为外泌体研究而设计；

2. 无菌采集的健康胎牛血清过滤法去除外泌体；

3. 胎牛血清内源外泌体去除率达97%；

4. 过滤法可有效保护FBS中重要的细胞营养因子；

5. Exo-FBS培养的细胞生长速率与形态与普通FBS无差异 。

|   产品质控

（FBS ：常规胎牛血清 ，Exo-FBS ：去外泌体血清）

  图1 A549细胞在常规FBS和Exo-FBS中生长情况一致

 图2 Western blot结果显示Exo-FBS中TSG101含量显著降低

|   产品说明

       细胞在含常规FBS培养基中培养一定时间 ，细胞融合度约为60% - 70%时 ，移去原有含FBS的培养基 ，换成新鲜的含无外泌体血清的培养基 ，继续培养48h左右 ，细胞融合度达到80%-95%左右时 ，收取上清用于提取外泌体 。
