產(chǎn)品介紹 E3 ubiquitin-protein ligase
which accepts ubiquitin from E2 ubiquitin-conjugating enzymes UBE2L3 and UBE2L6
in the form of a thioester and then directly transfers the ubiquitin to
targeted substrates such as LCMT2, thereby promoting their degradation. Induces
apoptosis via a p53/TP53-dependent but caspase-independent mechanism. However,
its overexpression also produces a decrease of the ubiquitin-dependent
stability of BAX, a pro-apoptotic protein, ultimately leading to protection of
cell death; But, it is not an anti-apoptotic protein per se.
Tissue specificity:
Broadly expressed, with lowest levels in brain and thymus, and highest levels
detectable in heart, ovary and testis.
Function:
E3 ubiquitin-protein ligase which accepts ubiquitin from E2 ubiquitin-conjugating enzymes UBE2L3 and UBE2L6 in the form of a thioester and then directly transfers the ubiquitin to targeted substrates such as LCMT2, thereby promoting their degradation. Induces apoptosis via a p53/TP53-dependent but caspase-independent mechanism.

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(yè)p傷。然而,抗體可通過(guò)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(guò)經(jīng)典途徑激活補(bǔ)體,凝聚的IgA、IgG4和IgE可通過(guò)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(guò)胎盤(pán)及粘膜:免疫球蛋白G(IgG)能通過(guò)胎盤(pán)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(guò)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??贵w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(guò)程:
1.免疫原:普通的大分子蛋白,通過(guò)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(jiàn)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。
5E3泛素蛋白連接酶144B/環(huán)指蛋白144B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。
