簡要描述：磷酸化轉(zhuǎn)錄因子RelB蛋白抗體注意事項(xiàng)；This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. Function: NF-kappa-B is a pleiotropic transcription factor which is present in almost all cell types and is involved in many biological processed such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. NF-kappa-B heterodimeric RelB-p50 and RelB-p52 complexes are transcriptional activators. RELB neither associates with DNA nor with RELA/p65 or REL. Stimulates promoter activity in the presence of NFKB2/p49. As a member of the NUPR1/RELB/IER3 survival pathway, may provide pancreatic ductal adenocarcinoma with remarkable resistance to cell stress, such as starvation or gemcitabine treatment.

Function:
NF-kappa-B is a pleiotropic transcription factor which is present in almost all cell types and is involved in many biological processed such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity.

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
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. 免疫動物：常用于制備抗血清的動物有豚鼠、家兔、雞、大小鼠等，大量生產(chǎn)時需要用到狗、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. 磷酸化轉(zhuǎn)錄因子RelB蛋白抗體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年而不會影響效價，而真空干燥保存時間可以更久。保存前需經(jīng)除菌并添加防腐劑。
