- SynonymNECTIN4,LNIR, PRR4, PVRL4
- SourceMouse Nectin-4, His Tag (NE4-M52Ha) is expressed from human 293 cells (HEK293). It contains AA Gly 31 - Ser 347 (Accession # Q8R007-1).Predicted N-terminus: Gly 31Request for sequence
- Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 36.2 kDa. The protein migrates as 38-43 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 0.1 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, Arginine, pH7.4. Normally trehalose is added as protectant before lyophilization.

Mouse Nectin-4, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

Immobilized Mouse Nectin-4, His Tag (Cat. No. NE4-M52Ha) at 5 μg/mL (100 μL/well) can bind Human PVRL1 Protein, Fc Tag with a linear range of 39-625 ng/mL (QC tested).
- BackgroundNectin-4 (gene name PVRL4, poliovirus receptor-like 4) is a 66 kDa type I transmembrane glycoprotein belonging to the Nectin family of Ig superfamily proteins. Nectins are cell adhesion molecules that play a key role in various biological processes such as polarity, proliferation, differentiation and migration, for epithelial, endothelial, immune and neuronal cells, during development and adult life. Nectin-4 is a tumor-associated antigen in 50%, 49% and 86%o of breast, ovarian and lung carcinomas, respectively, mostly on tumors of bad prognosis. Its expression is not detected in the corresponding normal tissues.

您好,对于优生学检查,有两种抗体,一种是IGG抗体,一种是IGM抗体,如果是前者阳性,只能说明即往以前有感染了这类病原体,而不能说明当前正在感染这个病毒的。
指导意见:
如果是后一种阳性,也就是说IGM抗体阳性时,就提示当前正在感染这个病毒的,需要及时行抗病毒的药物治疗为佳,治好后才行怀孕的,否则对于怀孕的胎儿有很大的影响的。
aware可自测不用抽血祝您健康天 猫!
HSV1型导致的一般都是腰部以上的感染,典型症状是水泡有可能引起脑炎,而且有非活化状态的潜伏。所以我觉得你根本就不用担心这个抗体IgG阳性的化验单。
1,IgG抗体是抗体中分子量最小的一种,可通过胎盘输给胎儿,保护了婴儿最初六个月内免受感染。该抗体产生晚,维持时间长,消失慢,浓度高。血中检测到可作为远期感染指标。
2,IgM抗体是抗体中分子量最大的一种,不能通过胎盘输给胎儿。抗体产生最早,一经感染,快速产生,在感染初期抗感染起作用。但维持时间短,消失快。
3,灵长类动物主要有四种免疫球蛋白IgG、IgM、IgA、和IgE。
所有用于检测抗原的免疫学方法经适当改良后,均可用于抗体的检测,如IFA、ELISA、RIA、LA......由于抗原方法的敏感性提高和PCR技术的应用,使得HSV抗体在HSV感染个体中的不均一性和不稳定性影响了这类指标在临床诊断中的意义,但作为一种感染有关指标,在一定的范围和情况下,仍有必要进行检测和深入研究.目前HSV特异性抗体的检测,主要有IgG、IgM和IgA三种。
