Monocytes (Mo) are immature phagocytic cells circulating in the blood. Acting as antigen-presenting immune cells, they can phagocytize and degrade microbes and particulate matter. Monocytes can differentiate into several different cell types. The most common applications for Monocytes are the in vitro differentiation into monocyte-derived dendritic cells (moDC), macrophages, and osteoclasts as well as their use as phagocytic immune cells in immunology and infection biology.
CD14 belongs to the family of LPS receptor antigens and is strongly expressed on the majority of Monocytes. Thus, binding of immunomagnetic particles to this antigen is employed for purification of PromoCell CD14 -Monocytes (hMoCD14 -PB) from Mononuclear Cells (MNC).
PromoCell Human CD14 Monocytes are isolated from fresh peripheral blood. After isolation of the ultra-pure mononuclear cell fraction by proprietary methods, the CD14 Monocytes are isolated by positive selection with > 95% purity.
NEW: Our hMoCD14+ -PB are now also available from HLA-typed donors.
Available formats:
- Cryopreserved: Cryogenic vial containing 10.000.000 viable cells.
- Cell pellet: 1 million cells dissolved in 200µl RNAlater© for subsequent RNA, DNA or protein analysis. Cell pellets cannot be revived.
| Recommended plating density | 1,000,000 cells per ml |

看有关产前诊断的一个资料,提到:“凡是酶活性能在成纤维细胞中表达均可用绒毛或羊水细胞的酶活性测定进行产前诊断,如溶酶体贮积症。”
不太理解,为什么成纤维细胞中表达的酶就能在绒毛或羊水细胞中测出来呢?绒毛的细胞跟成纤维细胞没什么直接关系吧?或者是因为成纤维细胞脱落到羊水中,破裂,然后就可以检测了?
求各位解答,谢谢。
三种酶分别反映肝脏的不同病理过程:
ALT增高往往说明肝实质细胞的损伤;GGTP增高可以说明胆汁淤积和对肝的“诱导作用”;测定CHE可以检查肝脏的蛋白合成功能。
反应的催化剂,或在某种代谢合成反应链中起辅助作用的。
它只是一个检验科的检验设备,用来化验血液、尿液中的成分浓度,医生据此来诊断疾病,可以查很多项目,如乙肝五项等等,不能直接检查什么疾病。
