This antibody reacts with the first EGF repeat in the extracellular domain of Ep-CAM. It is a 40-43kDa transmembrane epithelial glycoprotein, also identified as epithelial specific antigen (ESA), or epithelial cellular adhesion molecule (Ep-CAM). It is expressed on baso-lateral cell surface in most simple epithelia and a vast majority of carcinomas with the exception of adult squamous epithelium, hepatocytes and gastric epithelial cells. This antibody has been used to distinguish adenocarcinoma from pleural mesothelioma and hepatocellular carcinoma. This antibody is also useful in distinguishing serous carcinomas of the ovary from mesothelioma.
Does not react with rat and ferret.
MW : 40-43kDa; Positive Control : HT29 cells or breast tumor;Flow Cytometry (0.5-1ug/million cells); Immunofluorescence (1-2ug/ml); Western Blotting (0.5-1ug/ml); Immunohistology (Formalin-fixed) (0.5-1ug/ml for 30 min at RT),(Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes),Optimal dilution for a specific application should be determined.
For Research Use Only. Not for use in diagnostic/therapeutics procedures.
| Subcellular location: | Lateral cell membrane, Cell junction |
| Post transnational modification: | Hyperglycosylated in carcinoma tissue as compared with autologous normal epithelia. Glycosylation at Asn-198 is crucial for protein stability. |
| BioGrid: | 110250.5 interactions. |

我想用酶联免疫斑点(ELISPOT)技术测定NK细胞活性,但不知道哪里能买到试剂盒,特向大家求助,谢谢。
用Mabteck公司的ALP标记抗体吧,配合Millipore公司的Multiscreen-IP96孔板,所有的试剂都可以减半,照样可以出非常好的结果,4*96孔的试剂盒我一直做8*96孔,但BCIP/NBT显色液没试过减半,因为它很便宜。记得当年第一次做实验就出了很好的结果,经过不断摸索,做出的蓝紫色斑点确实非常漂亮,几乎没有非特异斑点,嗯,ELISPOT是我最拿手的实验之一。
关于PBMC:
拿到血液标本后,首先我要做的是尽快分离PBMC(一般2h内),国产的分离液里天津灏洋的比较好,然后用冻存液冻存PBMC。PBMC的冻存过程比一般的细胞株要更为严格,最好用冻存器。ELISPOT试验的第一天,在包被抗体的同时,将细胞复苏,完全培养液培养过夜,第二天收集细胞并计数即可。
请问一般的实验室可以进行ELIspot吗?(我可以买到现成的试剂盒,资金这个应该没有问题。)ELIspot的难点在哪里?多谢大虾们的指点!这个对我很重要,多谢!!!
