產(chǎn)品介紹 This gene encodes a serine/threonine
protein kinase activated by proapoptotic molecules indicating the encoded
protein functions as a growth suppressor. Cleavage of the protein product by
caspase removes the inhibitory C-terminal portion. The N-terminal portion is
transported to the nucleus where it homodimerizes to form the active kinase
which promotes the condensation of chromatin during apoptosis. Multiple
transcript variants encoding different isoforms have been found for this gene.
[provided by RefSeq, Jan 2012]
The human serine/threonine kinase, mammalian STE20 like kinase (MST), is considerably homologous to the budding yeast kinases, SPS1 and STE20, throughout their kinase domains. When stably expressed in HeLa cells, MST highly sensitizes the cells to death receptor mediated apoptosis by accelerating caspase 3 activation. These findings suggest that MST1 and MST2 play a role in apoptosis both upstream and downstream of caspase activation. MST1 is cleaved and activated by caspases during apoptosis and is capable of inducing apoptotic morphological changes such as chromatin condensation upon overexpression. Mammalian Sterile 20 Like 2 (MST2) is most similar to the previously identified MST1 protein kinase (78% identity, 88% similarity). Northern analysis indicates that MST2 mRNA is expressed at high levels in adult kidney, skeletal and placental tissues and at very low levels in adult heart, lung, liver and brain tissues. An in vitro kinase assay indicates that MST2 can phosphorylate an exogenous substrate, as well as itself, and phospho amino acid analysis indicates that it is a serine/threonine protein kinase.
實驗流程：
（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.蛋白激酶MST1/2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。
