產(chǎn)品介紹 Ubiquitin, a highly conserved
protein that has a major role in targeting cellular proteins for degradation by
the 26S proteosome, is synthesized as a precursor protein consisting of either
polyubiquitin chains or a single ubiquitin fused to an unrelated protein. This
gene encodes a fusion protein consisting of ubiquitin at the N terminus and
ribosomal protein S27a at the C terminus. When expressed in yeast, the protein
is post-translationally processed, generating free ubiquitin monomer and
ribosomal protein S27a. Ribosomal protein S27a is a component of the 40S
subunit of the ribosome and belongs to the S27AE family of ribosomal proteins.
It contains C4-type zinc finger domains and is located in the cytoplasm.
Pseudogenes derived from this gene are present in the genome. As with ribosomal
protein S27a, ribosomal protein L40 is also synthesized as a fusion protein
with ubiquitin; similarly, ribosomal protein S30 is synthesized as a fusion
protein with the ubiquitin-like protein fubi. Multiple alternatively spliced
transcript variants that encode the same proteins have been identified.[provided
by RefSeq, Sep 2008].
Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-6-linked may be involved in DNA repair; Lys-11-linked is involved in ERAD (endoplasmic reticulum-associated degradation) and in cell-cycle regulation; Lys-29-linked is involved in lysosomal degradation; Lys-33-linked is involved in kinase modification; Lys-48-linked is involved in protein degradation via the proteasome; Lys-63-linked is involved in endocytosis, DNA-damage responses as well as in signaling processes leading to activation of the transcription factor NF-kappa-B. Linear polymer chains formed via attachment by the initiator Met lead to cell signaling. Ubiquitin is usually conjugated to Lys residues of target proteins, however, in rare cases, conjugation to Cys or Ser residues has been observed. When polyubiquitin is free (unanchored-polyubiquitin), it also has distinct roles, such as in activation of protein kinases, and in signaling.
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。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(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。
5RPS27A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。
