商品介绍
Human Anti-Natalizumab Antibody, clone AbD21375 is a paratope specific, anti-idiotypic antibody that specifically recognizes free natalizumab but not free human alpha-4/beta-1 integrin or the drug/integrin complex. It inhibits the binding of natalizumab to its target and can be used to measure levels of free natalizumab and biosimilar products in bioanalytical and patient monitoring assays.A pair of anti-natalizumab antibodies can be used to develop a pharmacokinetic (PK) bridging assay to measure free drug. This antibody, in monovalent Fab format, is recommended as a capture antibody, paired with an HRP conjugated Anti-Natalizumab Antibody in full immunoglobulin format, clone AbD21375_hlgG1 (HCA249) as the detection antibody.Natalizumab (Tysabri) is a humanized IgG4/kappa monoclonal antibody approved as a monotherapy for the treatment of relapsing forms of multiple sclerosis and for the treatment of Crohn’s disease. It is directed against alpha-4 integrin (CD49d), and binds to alpha-4/beta-1 integrin on the surface of circulating leucocytes, except neutrophils. It is believed to act by blocking the interaction of alpha-4/beta-1 integrin with vascular cell adhesion molecule-1 (VCAM-1), preventing the adherence and transport of inflammatory immune cells across the intestinal lining and blood-brain barrier.View a summary of all anti-natalizumab antibodies

品牌介绍
AbD Serotec一抗以高特异性和亲和力直接结合特异性抗原。它们可以是与特定表位结合的单克隆抗体，也可以是与抗原的几个表位结合的多克隆抗体。一抗主要用于免疫测定，例如ELISA，蛋白质印迹，免疫组织化学，染色质免疫沉淀（ChIP）或流式细胞仪。对于抗原检测，可以将一抗结合到报告酶或荧光团上，这有助于定量或分析抗原表达。共轭一抗体通常消除了对二抗体的需求 ; 但是某些实验条件可能需要使用它们。针对纯化的一抗的Fc部分开发了二抗，通常将二抗结合用于抗原检测。另外，它们针对第一抗体的宿主物种而开发，使得在山羊中产生的第一抗体将需要在除山羊以外的物种中产生的抗山羊第二抗体。多克隆抗体由免疫球蛋白分子的混合池组成，这些免疫球蛋白分子与单个抗原上的几种不同表位结合。多克隆抗体通常在兔，驴，绵羊和山羊中产生，并从血清中纯化。相反，单克隆抗体结合靶抗原内的单个表位。
