簡要描述：磷酸化絲裂原活化的蛋白激酶p38β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: Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK11 is one of the four p38 MAPKs which play an important role in the cascades of cellular responses evoked by extracellular stimuli such as proinflammatory cytokines or physical stress leading to direct activation of transcription factors. Accordingly, p38 MAPKs phosphorylate a broad range of proteins and it has been estimated that they may have approximately 200 to 300 substrates each. MAPK11 functions are mostly redundant with those of MAPK14. Some of the targets are downstream kinases which are activated through phosphorylation and further phosphorylate additional targets. RPS6KA5/MSK1 and RPS6KA4/MSK2 can directly phosphorylate and activate transcription factors such as CREB1, ATF1, the NF-kappa-B isoform RELA/NFKB3, STAT1 and STAT3, but can also phosphorylate histone H3 and the nucleosomal protein HMGN1. RPS6KA5/MSK1 and RPS6KA4/MSK2 play important roles in the rapid induction of immediate-early genes in response to stress or mitogenic stimuli, either by inducing chromatin remodeling or by recruiting the transcription machinery. On the other hand, two other kinase targets, MAPKAPK2/MK2 and MAPKAPK3/MK3, participate in the control of gene expression mostly at the post-transcriptional level, by phosphorylating ZFP36 (tristetraprolin) and ELAVL1, and by regulating EEF2K, which is important for the elongation of mRNA during translation. MKNK1/MNK1 and MKNK2/MNK2, two other kinases activated by p38 MAPKs, regulate protein synthesis by phosphorylating the initiation factor EIF4E2. In the cytoplasm, the p38 MAPK pathway is an important regulator of protein turnover. For example, CFLAR is an inhibitor of TNF-induced apoptosis whose proteasome-mediated degradation is regulated by p38 MAPK phosphorylation. Ectodomain shedding of transmembrane

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. 磷酸化絲裂原活化的蛋白激酶p38β抗體免疫血清的收集：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. 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。
