注意事项：

1. HepG2细胞复苏或传代后会有少部分的细胞贴壁和部分悬浮的细胞，复苏两天后细胞会从贴壁细胞向外开始生长。在生长过程中，细胞会在贴壁细胞的上方生长，形成不同的细胞层

2. 在细胞复苏的一周内，培养瓶中会有悬浮的活细胞团，在换液过程中不要丢弃这些活的悬浮细胞，可以通过离心（125×g）回收细胞，重新接种到培养瓶中，分离或者丢弃漂浮的活细胞会使细胞数量变少，引起细胞的停滞生长或细胞死亡。

3. 培养条件的细微变化，尤其是pH和培养基中血清的质量，可能会影响细胞的生长状况，在细胞的生长过程中会有细胞内的液泡出现，特别在细胞快要融合是会出现这种情况。培养细胞时使用未被灭活的高质量、低内毒素的胎牛血清，可以使细胞更好的贴壁和形成单层细胞。细胞在生长过程中可以通过将血清浓度提到到20%来改善细胞生长缓慢的情况。

收货当天如何处理细胞？

收到细胞后请务必仔细阅读产品资料，了解细胞相关信息，如贴壁特性 (贴壁/悬浮/半贴壁半悬浮)、细胞形态、培养体系、传代比例和换液频率等。
