产品介绍 The breast cancer susceptibility gene (BRCA1) localizes to chromosome 17q. Mutations within this gene account for approximately 45% of families with high incidence of breast cancer and at least 80% of families with increased incidence of both early-onset breast cancer and ovarian cancer. A second breast cancer susceptibility gene, BRCA2, located on chromosome 13q12-13, also confers a high incidence of breast cancer, but unlike BRCA1, BRCA2 does not confer a substantially elevated risk of ovarian cancer. The BRCA2-Associated Factor 35 (BRAF35) protein forms a complex with BRCA2, which associates with condensed chromatin during histone H3 phosphorylation. BRAF35 expression levels are highest in proliferating tissues and parallel BRCA2 expression patterns. The structure of BRAF35 includes a kinesin-like coiled coil domain and a nonspecific DNA binding HMG domain. The chromatin localization of BRAF35 and antibody microinjection studies indicate a role for the BRAF35/BRCA2 complex in cell cycle regulation.
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。
