- SynonymCEACAM1,CD66a,BGP,BGP1,BGPI
- SourceHuman CEACAM-1, His Tag (CE1-H5220) is expressed from human 293 cells (HEK293). It contains AA Gln 35 - Gly 428 (Accession # AAH14473).Predicted N-terminus: Gln 35Request for sequence
- Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 44.1 kDa. The protein migrates as 57-100 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>92% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human CEACAM-1, 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 92%.

Immobilized Human CEACAM-1, His Tag (Cat. No. CE1-H5220) at 10 μg/mL (100 μL/well) can bind Biotinylated Human CEACAM-8, His,Avitag (Cat. No. CE8-H82E9) with a linear range of 0.039-1.25 μg/mL (QC tested).
- BackgroundCarcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is also known as Biliary glycoprotein 1 (BGP1), CD66a,which belongs to the immunoglobulin superfamily or CEA family. CEACAM1 /CD66a contains three Ig-like C2-type (immunoglobulin-like) domains and one Ig-like V-type (immunoglobulin-like) domain. CEACAM1 /CD66a was described as an adhesion molecule mediating cell adhesion via both homophilic and heterophilic manners, and was detected on leukocytes, epithelia, and endothelia. Studies have revealed that CEACAM1 / BGP-1 performs actions in multiple cellular processes including tissue differentiation, angiogenesis, apoptosis, metastasis, as well as the modulation of innate and adaptive immune responses.

患者,双手扶墙,脚尖着地;医生做好消毒,戴上手套,利用放血针(可以利用测血糖的放血针),在委中穴点刺放血,利用拔罐器把瘀血抽出来,直到见到新鲜血液为止。委中穴是解毒大穴。
中医强调治症不治病,虽然身体还有病毒,但是,只要症状能够解除,不影响正常生活和工作,就可以了。
需要强调:医生,一定要做好消毒、保护,防止病毒感染。 另外,可以把艾滋病作为一种疫病,尝试五苓散;五苓散是用来治疗疫病的。
核心抗原由183个或185个氨基酸组成,高度磷酸化,是乙肝病毒核心颗粒的唯一结构蛋白。正由于它存在于Dane颗粒核心结构表面,被表面抗原覆盖,故不易在血循环中检出。核心抗原具有强免疫原性,可诱导很强的体液免疫和细胞免疫,刺激机体产生抗-HBc。
e抗原为可溶性蛋白质,传染性强,游离存在于血液中,虽然很早就被发现,在病理上认为是HBV复制以具有强感染性的一个指标,但其功能尚不清楚。抗-HBe的出现,是预后良好的征象。向左转|向右转
主要是中度以上细胞免疫缺陷包括:CD4+T淋巴细胞耗竭,外周血淋巴细胞显著减少,CD4<200/μl,CD4/CD8<1.0,(正常人为1.25~2.1),迟发型变态反应皮试阴性,有丝分裂原刺激反应低下。NK细胞活性下降。
2.各种致病性感染的病原体检查
如用PCR方法检测相关病原体,恶性肿瘤的组织病理学检查。
3.HIV抗体检测
采用酶联免疫吸附法、明胶颗粒凝集试验、免疫荧光检测法、免疫印迹检测法、放射免疫沉淀法等,其中前三项常用于筛选试验,后二者用于确证试验。
4.PCR技术检测HIV病毒。
流感病毒的基因组包含________基因,其中__________蛋白可作为__________的结构基础.
我不知道第一空如何填,第二空是否应该填"HA蛋白"?第3空是否应该填"突变"?
多谢各位啊!
新年快乐!
万事如意!
1、存在于细胞外环境时,不显复制活性,但保持感染活性,是病毒体或病毒颗粒形式。
2、抗原,是指能够刺激机体产生(特异性)免疫应答,并能与免疫应答产物抗体和致敏淋巴细胞在体外结合,发生免疫效应(特异性反应)的物质
