A438079 is a selective small-molecule antagonist of human P2X7 receptor with IC50 value of 300 nM [1].The nucleotide receptor P2X7 receptor is a subtype of the P2X receptor family. It is expressed in cells of both the central nervous system and the immune system. Since the activation of P2X7 receptor by ATP is associated with the release of glutamate and cytokines, P2X7 receptor is thought to be a target of the treatment for inflammation and neurodegeneration. The tetrazole-based compound A438079 works as a competitive antagonist of P2X7 receptor and shows potent antinociceptive activity in rat model [2].A 438079 was selective against P2X7 receptor and showed no significant activity against other P2X receptors including P2X2, P2X3 and P2X4 even at concentration up to 10 μM. For other cell-surface ion channels and receptors, A 438079 also showed no effect. In the FLIPR assay using human 1321N1 astrocytoma cells stably transfected with recombinant rat or human P2X7 receptors, pretreatment of A 438079 potently inhibited the calcium influx with IC50 values of 100 and 300 nM, respectively. In human THP-1 cells differentiated with IFNγ and LPS, A 438079 treatment inhibited interleukin-1β release stimulated by BzATP with pIC50 value of 6.7.Besides that, A 438079 was found to block the pore formation in humanTHP-1 cells [1 and 2].In the rat model of neuropathic pain, administration of A 438079dose-dependently reduced the mechanical allodynia with ED50 value of 76 μM/kg. In mice with status epilepticus, administration of A 438079 resulted in decreased total seizure power, amplitude and reduced seizure behavior. In addition, A 438079 was found to attenuate acetaminophen-induced liver injury in mice [2, 3 and 4].References:[1] Donnelly-Roberts DL, Jarvis MF.

说得简单点就是，细胞核是原封不动的，没有重组过，而细胞核外的东西是很多别的细胞中提取出来的并组合起来的。这样的混合体淋巴细胞产生的抗体具有很强的嵌合能力，针对性比一般的抗体强，但是它的来源没变，所以称之为混合单克隆抗体
制备抗体都需要进行纯化处理
清冷冻干燥后保存。
没有marker，怎么知道你做的蛋白大小？
没有参照物，怎么知道你跑的快不快？
没有尺子，怎么知道你的size大小？
凭嘴说吗？
单克隆抗体这项新技术从根本上解决了在抗体制备中长期存在的特异性和可重复性问题，可用于探讨: ①蛋白质的精细结构；②淋巴细胞亚群的表面新抗原；③组织相容性抗原；④激素和药物的放射免疫（或酶免疫）分析；⑤肿瘤的定位和分类；⑥纯化微生物和寄生虫抗原；⑦免疫治疗和与药物结合的免疫-化学疗法 (“导弹”疗法,利用单克隆抗体与靶细胞特异性结合，将药物带至病灶部位.。
因此，单克隆抗体可直接用于人类疾病的诊断、预防、治疗以及免疫机制的研究，为人类恶性肿瘤的免疫诊断与免疫治疗开辟了广阔前景。
