商品介绍
Omalizumab (brand name Xolair®) is a recombinant DNA-derived humanized IgG1 kappa monoclonal antibody used in the treatment of patients with moderate or severe asthma who have demonstrated a positive allergy skin test and whose symptoms are not controlled by inhaled corticosteroids.Allergic asthma is mediated by IgE released by B cells in response to allergen. Circulating IgE binds to the high-affinity IgE Fc receptor (FcεRI) expressed on basophils and mast cells, triggering the release of histamine, leukotrienes and other mediators associated with the pathophysiology of asthma. Omalizumab is directed against the Fc region of human immunoglobulin E (IgE). By binding to circulating IgE at the site of FcεRI binding, this therapeutic antibody prevents the interaction of IgE with its receptor thus limiting mediator release. Treatment with omalizumab has also been demonstrated to reduce the expression of FcεRI on mast cells and basophils, providing additional clinical benefit.Human anti Omalizumab, clone AbD20760 is a Type 3 anti-idiotypic antibody that binds specifically to the drug/IgE complex. Clone AbD20760 does not recognise free omalizumab or free human IgE. Clone AbD20760 may be used to detect omalizumab captured via immobilized human IgE or to measure the level of drug/IgE complex in serum from patients.Other Type 3 (HCA237) and Type 1 (HCA235, HCA236) antibodies to omalizumab are also available from Bio-Rad in IgG1 and Fab formats. This range of anti omalizumab antibodies forms part of a wider and expanding portfolio of anti-idiotypic antibodies that have been developed for the detection of biotherapeutics.
Product Details
- Product Form
- A monovalent human recombinant Fab selected from the HuCAL® phage display library, expressed in E. coli. The antibody is tagged with a DYKDDDDK tag and a HIS-tag (HHHHHH) at the C-terminus of the antibody heavy chain. This antibody is supplied as a liquid.
- Preparation
- Metal chelate affinity chromatography
- Buffer Solution
- Phosphate buffered saline
- Preservative Stabilisers
- 0.01% Thiomersal
- Immunogen
- Omalizumab.
- Affinity
- The monovalent intrinsic affinity of HCA238 was measured as Kd = 0.58 nM by real time, label free molecular interaction analysis on immobilized omalizumab in complex with human IgE.
- Approx. Protein Concentrations
- IgG concentration 0.5 mg/ml
Storage Information
- Storage
- Store at +4oC or at -20oC if preferred.Storage in frost-free freezers is not recommended.This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.

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。
