抗体是广泛研究和体外诊断(IVD)应用的核心试剂。根据生产方法,它们可以分为多克隆或单克隆,也可以根据识别的靶标类型分为一抗和二抗。选择抗体时需要考虑的因素包括它们的验证严格程度,以及它们是否有足够的数量来满足特定项目的长期需求。

什么是单克隆抗体和多克隆抗体?

已建立的抗体生产方法是通过用目标抗原免疫动物来启动的。然后,抗原呈递细胞对其进行处理,使其能够通过循环B淋巴细胞进行检测,每个B淋巴细胞在其表面表达一种独特的抗体。在靶识别之后,B淋巴细胞进行克隆扩增并分泌可从血清中纯化的抗体。以这种方式产生的抗体被描述为多克隆的,因为所得产物包括来自多个B淋巴细胞的抗体,每个B淋巴细胞识别不同的表位。
作为这种方法的替代方案,可以分离B淋巴细胞并用于产生杂交瘤。通过在适当的培养基中稀释这些,使得多孔板的每个孔仅接收一个杂交瘤,可以测试细胞上清液并鉴定表现最好的克隆。通过这种方法产生的抗体被描述为单克隆抗体。
凯靖公司构建了基于全自动化高通量杂交瘤和单B细胞技术的单克隆抗体对发现平台。

一抗和二抗的区别是什么?

虽然一抗直接与特定抗原结合,如细胞骨架蛋白或细胞因子,但二抗用于间接检测。这意味着只有当一级抗体识别出它们的靶点后,它们才能结合一级抗体。二级抗体是通过用来自另一物种的抗体免疫动物而产生的,并且通常用于通过多种二级抗体与每种一级抗体的结合来提供信号扩增。

抗体选择注意事项

抗体选择需要考虑的因素包括是使用多克隆还是单克隆,是否需要直接或间接检测,以及将使用何种类型的应用。虽然酶如辣根过氧化物酶(HRP)通常用于比色或化学发光检测,但荧光团优选用于流式细胞术或免疫组织化学(IHC)等多重应用。至关重要的是,抗体试剂应被证明能特异性识别其靶抗原,而不会表现出不必要的交叉反应性。

靶标信息
功能Acts as a tumor suppressor in many tumor types; induces growth arrest or apoptosis depending on the physiological circumstances and cell type. Involved in cell cycle regulation as a trans-activator that acts to negatively regulate cell division by controlling a set of genes required for this process. One of the activated genes is an inhibitor of cyclin-dependent kinases. Apoptosis induction seems to be mediated either by stimulation of BAX and FAS antigen expression, or by repression of Bcl-2 expression. Implicated in Notch signaling cross-over. Isoform 2 enhances the transactivation activity of isoform 1 from some but not all TP53-inducible promoters. Isoform 4 suppresses transactivation activity and impairs growth suppression mediated by isoform 1. Isoform 7 inhibits isoform 1-mediated apoptosis.
细胞定位Cytoplasm; Cytoplasm. Nucleus. Nucleus > PML body. Endoplasmic reticulum. Interaction with BANP promotes nuclear localization. Recruited into PML bodies together with CHEK2; Nucleus. Cytoplasm. Localized in both nucleus and cytoplasm in most cells. In some cells, forms foci in the nucleus that are different from nucleoli; Nucleus. Cytoplasm. Localized in the nucleus in most cells but found in the cytoplasm in some cells; Nucleus. Cytoplasm. Localized mainly in the nucleus with minor staining in the cytoplasm; Nucleus. Cytoplasm. Predominantly nuclear but localizes to the cytoplasm when expressed with isoform 4 and Nucleus. Cytoplasm. Predominantly nuclear but translocates to the cytoplasm following cell stress.
序列相似性Belongs to the p53 family.
结构域The nuclear export signal acts as a transcriptional repression domain. The TADI and TADII motifs (residues 17 to 25 and 48 to 56) correspond both to 9aaTAD motifs which are transactivation domains present in a large number of yeast and animal transcription factors.
