Factor XI / FXI / F11抗体
抗体类型: Mouse Monoclonal Antibody ( Mouse mAb Service Platform )
克隆号 : 2B7E12F8
抗体宿主 : Mouse 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.
制备方法 : This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, human cell-derived, recombinant human Factor XI ( rh Factor XI ; Catalog#10302-H08H ; NP_000119.1 ; Met 1- Val 625 ). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
Factor XI / FXI / F11抗体背景综述
Factor XI (plasma thromboplastin antecedent) is a plasma glycoprotein, and a zymogen acting as a serine protease which participates in blood coagulation as a catalyst in the conversion of factor IX to factor IXa in the presence of calcium ions. The factor XI is synthesized in the liver as a single polypeptide chain with a molecular weight estimated between 125 ~160 kDa and then is processed into a disulfide-bond linked homodimer. Factor XI is is converted to an active protease, factor XIa, by factor XIIa ( or factor XII) in the presence of high molecular weight kininogen (HMWK) and a polyanionic surface. After the activation reaction, Factor XIa is composed of two heavy and two light chains held together by three disulfide bonds. The heavy chains are derived from the amino termini of the zymogen and responsible for the binding of factor XI to high molecular weight kininogen and for the activation of factor IX, while the light chain contains the catalytic portion of the enzyme and is homologous to the trypsin family of serine proteases. FXI deficiency is a disorder characterized by a mild or no bleeding tendency. The vast majority of the FXI deficiencies have been found in the Ashkenazi Jewish population.

Factor XI (FXI) is the zymogen precursor of an active serine protease that participates in the contact phase of coagulation. Synthesized in the liver, it circulates in the plasma in a noncovalent complex with high molecular weight kininogen
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
