CD86 / ETC-1 / B7-2抗体
抗体类型: Rabbit Polyclonal Antibody ( Antibody Purification Platform )
抗体宿主 : Rabbit IgG
缓冲液 : 0.2 μm filtered solution in PBS, 5% trehalose may be added in some batches. Please read the hardcopy of COA or contact our customer service to confirm the formulation.

CD86 / ETC-1 / B7-2抗体背景综述
Mouse CD86, also known as B-lymphocyte activation antigen B7-2 (referred to as B70), is a member of the cell surface immunoglobulin superfamily and is constitutively expressed on interdigitating dendritic cells, Langerhans cells, peripheral blood dendritic cells, memory B cells, and germinal center B cells. B7-2 exists predominantly as a monomer on cell surfaces and interacts with two co-stimulatory receptors CD28 and cytotoxic T lymphocyte -associated antigen 4 (CTLA-4) expressed on T cells, and thus induces the signal pathways which regulate T cell activation and tolerance, cytokine production, and the generation of CTL. CD28 has two ligands expressed largely on professional APC, named B7-1 (CD80) and B7-2 (CD86). They are both type I transmembrane proteins with a membrane distal IgV and a membrane proximal Ig constant (IgC) domain and share 25% sequence identity. Although interacting with the same receptors, B7-1 and B7-2 show several distinct features. Binding of B7-2 with CD28 induces the activation of T cell, whereas CTLA-4 acts as a negative regulator and diminishes the immune responses. It is indicated that contacts between B and T helper cells mediated by CD86 encourage signals for the proliferation and IgG secretion of normal B cells and B cell lymphomas. Recent study has revealed that CD86 also promotes the generation of a mature APC repertoire and promotes APC function and survival. CD86 has an important role in chronic hemodialysis, allergic pulmonary inflammation, arthritis, and antiviral responses, and thus is regarded as a promising candidate for immune therapy.

文献和实验人转录因子E2F1 ( E2F1 )ELISA 试剂盒 原理 本实验采用双抗体夹心 ABC-ELISA 法。用抗人 E2F1 单抗包被于酶标板上，标准品和样品中的 E2F1与单抗结合，加入生物素化的抗人 E2F1 ，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，最后加终止液硫酸，在 450nm 处测 OD 值，E2F1 浓度与 OD 值成正比
X性联无丙种球蛋白血症(X-linked agammagl，bulinemia，XLA)是临床上首次确定的体液免疫缺陷病，由Brutor于1952年报道，故又称Bruton病。XLA作为常见的原发性免疫缺陷病之一，特点为血清中各类免疫球蛋白缺乏，或只能测得微量的抗体。外周血和淋巴组织中B细胞减少或完全缺乏，淋巴结中无生发中心和浆细胞。本病起病早，在出生数月后当患儿体内的母源性抗体水平下降时开始发病。临床表现为反复化脓性感染，患者细胞免疫功能不受影响(部分患者有T细胞数量减少)，主要缺陷
ChIP是一种强大的确定蛋白或者组蛋白修饰在基因组上定位的实验方法。染色质被分离出来后采用抗体与抗原的结合来判定目的蛋白是否结合在特定的DNA序列上或者判定目的蛋白结合位点在全基因组范围的分布（微阵列或DNA序列）。这种方法具有空间性与时效性。该实验设计为如何在细胞中进行ChIP实验提供了详细的步骤。1. 交联和细胞收获甲醛可以将蛋白质交联到DNA上。交联结果的好坏决定于交联时间的把握。我们建议样品交联的时间一般为2-30分钟。过度的交联会减少抗原的结合性和超声断裂的效率。抗原决定簇也会被掩盖
