Hepatocytes derived from human induced pluripotent stem (hiPS) cells using the Cellartis iPS Cell to Hepatocyte Differentiation System are an alternative to primary hepatocytes, as they exhibit sufficient expression levels of drug-metabolizing enzymes and transporters and demonstrate stable functionality over time in culture. In addition, hiPS cell-derived hepatocytes can provide an accurate reflection of the metabolic diversity observed in the human population.
Hepatocytes derived from human induced pluripotent stem (hiPS) cells using the Cellartis iPS Cell to Hepatocyte Differentiation System are an alternative to primary hepatocytes, as they exhibit sufficient expression levels of drug-metabolizing enzymes and transporters and demonstrate stable functionality over time in culture. In addition, hiPS cell-derived hepatocytes can provide an accurate reflection of the metabolic diversity observed in the human population. The Cellartis iPS Cell to Hepatocyte Differentiation System provides a complete solution for generating functional, hiPS cell-derived hepatocytes within three weeks.
The process of generating hiPS cell-derived hepatocytes begins with the directed differentiation of hiPS cells into Definitive Endoderm (DE) cells that are then differentiated further into hepatocytes. The complete system provides media and ready-to-use coatings for each step of the iPS-cell-to-hepatocyte differentiation protocol. Starting with approximately 3 x 106 undifferentiated hiPS cells, this system yields 5 x 106 hepatocytes, equivalent to a confluent monolayer of 50 cm2. This do-it-yourself system offers a solution for the consistent production of assay-ready cells from patient-derived cells or from Cellartis brand iPS cell lines—enabling highly reproducible results.
Hepatocytes obtained with the Cellartis iPS Cell to Hepatocyte Differentiation System express major hepatic markers and show relevant CYP enzyme activities based on the genetic background of the original hiPS cells from which they were derived. In addition, these freshly differentiated hepatocytes are functionally stable for a longer timeframe compared to cryopreserved primary hepatocytes, enabling prolonged experiments such as long-term toxicity assays or viral infection studies. Cellartis Hepatocyte Maintenance Medium (Cat. # Y30051) is recommended for long-term maintenance of hiPS cell-derived hepatocytes.

尽量使用已经用荧光素标记好的单克隆抗体。
如果是单色实验，荧光素的亮度越强越好，比如标记了APC的抗体就要比标记了pacific blue的在相同抗原量，抗体用量相同的情况下，要亮很多
如果是多色实验，除了不要使用光谱重叠度高的荧光素以外，还要搭配染色指数。简单的说，就是用亮度强的荧光素标记的抗体来染水平低的抗原，而用较弱的荧光素标记的抗体来染高表达的抗原。

如果一个抗体可以用来“做western blot，免疫荧光，免疫共沉淀,ELISA”，我估计着是HRP或碱性磷酸酶或生物素之类标记的，然后需要再加荧光标记的二抗，这类抗体也是不能做流式用的。
我只用过流式的抗体来做免疫荧光（直接染色），效果还不错，但是反过来就没试过。
楼上两位还是要仔细看下产品说明书
