簡(jiǎn)要描述：銜接蛋白β抗體注意事項(xiàng)；This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. Function: Component of the adaptor protein complex 2 (AP-2). Adaptor protein complexes function in protein transport via transport vesicles in different membrane traffic pathways. Adaptor protein complexes are vesicle coat components and appear to be involved in cargo selection and vesicle formation. AP-2 is involved in clathrin-dependent endocytosis in which cargo proteins are incorporated into vesicles surrrounded by clathrin (clathrin-coated vesicles, CCVs) which are destined for fusion with the early endosome. The clathrin lattice serves as a mechanical scaffold but is itself unable to bind directly to membrane components. Clathrin-associated adaptor protein (AP) complexes which can bind directly to both the clathrin lattice and to the lipid and protein components of membranes are considered to be the major clathrin adaptors contributing the CCV formation. AP-2 also serves as a cargo receptor to selectively sort the membrane proteins involved in receptor-mediated endocytosis. AP-2 seems to play a role in the recycling of synaptic vesicle membranes from the presynaptic surface. AP-2 recognizes Y-X-X-[FILMV] (Y-X-X-Phi) and [ED]-X-X-X-L-[LI] endocytosis signal motifs within the cytosolic tails of transmembrane cargo molecules. AP-2 may also play a role in maintaining normal post-endocytic trafficking through the ARF6-regulated, non-clathrin pathway. The AP-2 beta subunit acts via its C-terminal appendage domain as a scaffolding platform for endocytic accessory proteins; at least some clathrin-associated sorting proteins (CLASPs) are recognized by their [DE]-X(1,2)-F-X-X-[FL]-X-X-X-R motif. The AP-2 beta subunit binds to clathrin heavy chain, promoting clathrin lattice assembly; clathrin displaces at least some CLASPs from AP2B1 which probably then can be positioned for further coat assembly.

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)胎盤及粘膜：免疫球蛋白G（IgG）能通過(guò)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(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. 銜接蛋白β抗體免疫原：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。
5. 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。
