產(chǎn)品介紹 Cytomegalovirus is a member of
the herpes virus group, which includes herpes simplex virus types 1 and 2,
varicella zoster virus (which causes chicken pox), and Epstein Barr virus
(which causes infectious mononucleosis). These viruses share a characteristic
ability to remain dormant within the body over a long period. CMV viral genes
are co-ordinately expressed in groups at various times after infection. Early
viral proteins are expressed in the nucleus of infected cells within 3 to 24
hours of infection prior to the commencement of viral DNA replication. This is
followed by expression of the early intermediate genes, which encode enzymes
required for viral DNA replication. After 48 to 72 hours, a number of late
viral antigens may be demonstrated in the nuclei and cytoplasm of infected
cells. pp65 is a 65kD phosphorylated glycoprotein and is the most abundant of
the late antigens.
Function:
Subunit:
Interacts with host
NCL/nucleolin. Interacts with host IFI16.
Subcellular
Location:
Virion tegument (Potential). Host nucleus. Host cytoplasm. Note=As part of the incoming virion, pp65 is targeted to the nucleus immediately after infection. The newly synthesized pp65 is observed in the nucleus until some time after 48 hours postinfection. Thereafter, pp65 is probably exported and accumulates in the cytoplasm. Also found in dense bodies.
實(shí)驗(yàn)流程:
(1)特異性結(jié)合抗原:抗體本身不能直接溶解或殺傷帶有特異抗原的靶細(xì)胞,通常需要補(bǔ)體或吞噬細(xì)胞等共同發(fā)揮效應(yīng)以清除病原微生物或?qū)е虏±頁p傷。然而,抗體可通過與病毒或毒素的特異性結(jié)合,直接發(fā)揮中和病毒的作用。
(2)活補(bǔ)體:IgM、IgG1、IgG2和IgG3可通過經(jīng)典途徑激活補(bǔ)體,凝聚的IgA、IgG4和IgE可通過替代途徑激活補(bǔ)體。
(3)結(jié)合細(xì)胞:不同類別的免疫球蛋白,可結(jié)合不同種的細(xì)胞,參與免疫應(yīng)答。
(4)可通過胎盤及粘膜:免疫球蛋白G(IgG)能通過胎盤進(jìn)入胎兒血流中,使胎兒形成自然被動(dòng)
免疫。免疫球蛋白A(IgA)可通過消化道及呼吸道粘膜,是粘膜局部抗感染免疫的主要因素。
(5)具有抗原性:抗體分子是一種蛋白質(zhì),也具有刺機(jī)體產(chǎn)生免疫應(yīng)答的性能。不同的免疫球蛋白分子,各具有不同的抗原性。
(6)抗體對(duì)理化因子的抵抗力與一般球蛋白相同:不耐熱,60~70℃即被破壞。各種酶及能使蛋白質(zhì)凝固變性的物質(zhì),均能破壞抗體的作用。抗體可被中性鹽類沉淀。在生產(chǎn)上??捎昧蛩徜@或硫酸鈉從免疫血清中沉淀出含有抗體的球蛋白,再經(jīng)透析法將其純化。
抗體的制備過程:
1.免疫原:普通的大分子蛋白,通過分子克隆構(gòu)建載體并在大腸桿菌中進(jìn)行誘導(dǎo)表達(dá)獲得重組蛋白,純化鑒定后可直接作為免疫原;小分子蛋白或化合物等分子量小,需要偶聯(lián)載體對(duì)該分子進(jìn)行改造才能使其成為具有免疫原性的抗原,常見偶聯(lián)載體如BSA、OVA、HAS等。
2. 免疫動(dòng)物:常用于制備抗血清的動(dòng)物有豚鼠、家兔、雞、大小鼠等,大量生產(chǎn)時(shí)需要用到狗、綿羊、山羊等。
3.免疫血清的收集:一般家兔、綿羊、山羊可采用靜動(dòng)脈采血,家兔、豚鼠、大鼠、雞可采用心臟采血,家兔、山羊、綿羊可采用靜脈采血。
4. 免疫血清的純化與鑒定:得到的抗血清需要進(jìn)一步的純化,利用偶聯(lián)了抗原的親和柱進(jìn)行層析,具有高效,特異性強(qiáng),純度高的特定。接著要鑒定純化蛋白的含量、相對(duì)分子的質(zhì)量、純度以及特異性。
5.人巨細(xì)胞病毒單克隆抗體免疫血清的保存:抗體一般比較穩(wěn)定,在-80℃ ~-20 ℃可以保存約5年而不會(huì)影響效價(jià),而真空干燥保存時(shí)間可以更久。保存前需經(jīng)除菌并添加防腐劑。
