| 产品介绍 | background: B7-H4 protein is expressed on the surface of a variety of immune cells and functions as a negative regulator of T cell responses. While B7-H4 mRNA is widely distributed in mouse and human peripheral tissues, cell surface expression of B7-H4 protein is limited and shows an inducible pattern on hematopoietic cells. Putative receptor of B7-H4 can be upregulated on activated T cells. By arresting cell cycle, B7-H4 ligation of T cells has a profound inhibitory effect on the growth, cytokine secretion, and development of cytotoxicity. Administration of B7-H4Ig into mice impairs antigen-specific T cell responses whereas blockade of endogenous B7-H4 by specific monoclonal antibody promotes T cell responses. B7-H4 thus may participate in negative regulation of cell-mediated immunity in peripheral tissues. Function: Negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. Involved in promoting epithelial cell transformation. Subcellular Location: cell membrane; Single-pass type I membrane protein (Potential). Note=Expressed at the cell surface. A soluble form has also been detected. Tissue Specificity: Overexpressed in breast, ovarian, endometrial, renal cell (RCC) and non-small-cell lung cancers (NSCLC). Expressed on activated T- and B-cells, monocytes and dendritic cells, but not expressed in most normal tissues (at protein level). Widely expressed, including in kidney, liver, lung, ovary, placenta, spleen and testis. Post-translational modifications: N-glycosylated. Similarity: Belongs to the immunoglobulin superfamily. BTN/MOG family. Contains 2 Ig-like V-type (immunoglobulin-like) domains.

B7-H4(B7 Homolog 4)是B7家族中的新成员,它能通过抑制T细胞的增殖、细胞因子的产生和细胞周期的进程来负性调控T细胞的免疫应答,其大量表达B7-H4还可以促进上皮细胞的恶性转化,保护表皮细胞免于失巢凋亡,在肿瘤的发生,进展和转归中发挥重要作用. 目前对B7-H4信号通路的进一步的研究必将为自身免疫性疾病、病毒感染性疾病和器官移植后排斥反应中T细胞介导的免疫应答调控提供了新的途径,同时也为肿瘤的诊断、治疗提供崭新的前景。 |

文献和实验人B7-H4 ( B7-H4 )ELISA 试剂盒 ( 用于血清、血浆、细胞培养上清液和尿液生物体液内 ) 原理 本实验采用双抗体夹心 ABC-ELISA 法。用抗人 B7-H4 单抗包被于酶标板上，标准品和样品中的 B7-H4与单抗结合，加入生物素化的抗人 B7-H4 ，形成免疫复合物连接在板上，辣根过氧化物酶标记的 Streptavidin 与生物素结合，加入底物工作液显蓝色，最后加终止
抗体的结构决定了其对应的功能，同一抗体的V区和C区的氨基酸组成和顺序不同，决定了其功能上的差异。V区和C区的组成和结构，决定了抗体的生物学功能。 图1：抗体的主要功能（图片来源：Abbas et al: Cellular and Molecular Immunology, 7e.) 1、特异性识别功能 抗体可以通过其结构上的可变区域与抗原结合，同时，具有极高的特异性。这种特异性识别功能可以使抗体识别和结合到感染的病原体，肿瘤细胞等不同种类的分子，帮助免疫系统识别并定位到这些分子，进而启动
在生命科学和医学基础研究中，或多或少都需要用到抗体。抗体的应用场景不同、标记物众多，且针对同一标记物市场上往往有多个抗体可供选择，那么，我们如何从成百万上千万种抗体中，挑选出我们想要的那支呢？ 在我们6月份的关于抗体的调研活动中，我们发现，大家更多的是去参考文献或专利中的材料和方法部分，这无疑很大程度上保证了抗体的有效性。其次有45%和34%的受访者会用到百度和谷歌，然而这两个搜索引擎覆盖面颇广，经常会出现抗体无关的搜索结果，而专业用于查找抗体的网站，大家却知之甚少。 因此，本次文章中
