产品介绍 Zinc-finger proteins contain DNA-binding domains and have a wide variety of functions, most of which encompass some form of transcriptional activation or repression. ZNF265 (Zinc finger protein 265), also known as ZRANB2 (Zinc finger Ran-binding domain-containing protein 2), ZIS, ZIS1 or ZIS2, is a 330 amino acid protein that belongs to the ZRANB2 family. Localized to the nucleus, ZNF265 functions as a splicing factor that is responsible for alternatively splicing Tra-2∫ (transformer-2 beta) transcripts and is thought to interfere with constitutive 5’-splice selection. ZNF265 contains two RanBP2-type zinc fingers through which it conveys its RNA-binding activity. Two isoforms, designated ZIS-1 and ZIS-2, are expressed due to alternative splicing events. Upon DNA damage, ZIS-2 may be phosphorylated by ATM or ATR.
抗原与抗体的关系
①抗体和相应的抗原结合后,可以促进白细胞的吞噬作用而将抗原消除,使抗原失去致病作用。
②一种抗体只能抵抗一种抗原,而且一种抗体只能受相应的抗原刺激后才能形成。
免疫的功能:
免疫具有三方面的功能:
①防御功能:抵抗抗原的侵入、防止疾病的产生。
②自我稳定:清除体内衰老、死亡和损伤的细胞。
③免疫监视:监视、识别和清除体内产生的异常细胞。
特别提醒:过敏反应:当人体抵抗抗原侵入的功能过强时,在过敏原(引起过敏反应的物质,如某些食物、药物)的刺激下,人体就会发生过敏反应。
1.抗体名称容易出错
抗体一般以抗原来命名,名称核对时最简单也最容易犯错,有些蛋白质有不同亚基(HIF-1α、HIF-1β);有些蛋白质有不同磷酸化状态,例如EGFR和p-EGFR的区别,等等。
除了蛋白质的名称外,有其他后缀。
2.多抗和单抗不同
单抗上面介绍过了,而多抗(polyclonal antibodies)一般用兔子、山羊等大型动物,因为多抗是直接从血液中纯化提取出来的,而不像单抗是用细胞培养出来的。
单克隆抗体的优点是产量持续稳定、特异性较高、但灵敏度不如多抗。如果对抗体的特异性要求高,用量较大或需要长期使用一致的抗体,制备的抗体应用要求多(WB/IP/IF/ICC等),可以选择单克隆抗体。
多抗的特异性较差,存在批间差(因为兔子的血被放光挂掉了,而山羊可以常年养着,放点血出来,在养几天再放血,好残忍),易造成背景,例如在WB中有杂带,在IHC中背景较深等等。但由于多抗识别多个抗原表位,对于丰度偏低的蛋白也更容易检出。
