Abcam’s Complement C3b Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Complement C3b concentrations in Human plasma, serum, urine, milk, saliva, CSF, cell lysate and cell culture supernatants. A Complement C3b specific antibody has been precoated onto 96-well plates and blocked.

Les 3 voies d'activation convergent en une voie finale commune lorsque la convertase C3 clive C3 en C3a et C3b (voir figure Voies d'activation du complément). Le clivage de C3 peut aboutir à la formation du complexe d'attaque de la membrane (MAC, membrane attack complex), le composant cytotoxique du système du complément.

Initiation of each pathway generates proteolytic enzyme complexes (C3 convertases) which are bound to the target surface. These enzymes cleave a peptide bond in C3 releasing the anaphylatoxin C3a and activating C3b. Forms the pro-C3-convertase enzyme complex by interacting with Complement factor B Bb fragment (Bb), which is then stabilized by binding CFP, allowing the complex to become active (By similarity). The interaction with Bb is dependent on Mg2+ (By similarity). C3b interacts with CR1 (via Sushi 8 and Sushi 9 domains). C3b interacts with CFH. The complement system can be activated via immune complexes, and the alternative pathway (properdin pathway), which is activated primarily by foreign bodies such as microorganisms. C3 activation involves cleavage by C3 convertase into C3a and C3b. The complement proteins C3b and to a lesser extent, C4b can function as opsonins, that is, they can attach antigens to phagocytes. The complement proteins C5b6789n, functions as a Membrane Attack Complex (MAC) causing lysis of Gram-negative bacteria, human cells displaying foreign epitopes, and viral envelopes.

C1q also binds, via its collagenous region, to a receptor, a widely distributed 60 kDa species (C1q-R). The C3b complement protein deposited on the pathogen's surface is broken down into C3d and C3c by Factor I alternative pathway C3d then binds to the CR2 receptor on B cell cross links the ag/Ig binding initiation of signaling through CD19 and activation of B cell. Complement C3b, Human, is a native C3b complement component. It is a glycoprotein composed of the modified C3-α chain (αʹ) (M.W. 105,000) and the intact C3-β chain (M.W. 75,000). Complement C3b, Human MSDS (material safety data sheet) or SDS, CoA and CoQ, dossiers, brochures and other available documents.

Polymorphisms in the complement receptor 1 (CR1) gene are associated with response to eculizumab. CR1, through binding C3b and C4b, enhances the decay of the C3 and C5 convertases. 18 The density of CR1 on the surface of red cells modulates binding of C3 fragments to the GPI-negative red cells when C5 is inhibited. PNH patients with

Macrophages and neutrophils recognize C3b by the complement receptor 1 (CR1, CD35). 補体（英:Complement）とは、生体が病原体を排除する際に抗体および貪食細胞を補助するという意味で命名された免疫システム (補体系) を構成するタンパク質であり、補体系の役割は大きく言って下記の3つから構成されるものである。 C3, the most abundant complement protein in blood, plays a central role in the activation sequence of the complement system as well as in host defense.

The C3b complement protein deposited on the pathogen's surface is broken down into C3d and C3c by Factor I alternative pathway C3d then binds to the CR2 receptor on B cell cross links the ag/Ig binding initiation of signaling through CD19 and activation of B cell.

C1q also binds, via its collagenous region, to a receptor, a widely distributed 60 kDa species (C1q-R). 2020-04-07 C3b itself is produced by all three pathways of complement (Law, S.K.A. and Reid, K.B.M.

(1) A pathogen coated in C3b binds to complement receptor 1 (CR1) expressed on the surface of phagocytes (including APCs).

Faktor H gör C3b tillgängligt för faktor I (tidigare kallat KAF, C3bINF eller enzym 3b-inaktivator), så att iC3b bildas. Därefter klyver faktor I och ett trypsinliknande proteolytiskt enzym iC3b i C3c och C3dg.

The majority of Klebsiella pneumoniae serum-resistant strains activate complement and bind C3b, the opsonic fragment of C3, without C5b-9 formation and bacterial killing. The mechanisms leading to C3b deposition without cell death were studied, and the results indicate that serum-resistant strains a …

Immune clearance; The complement system removes immune complexes from the circulation and deposits them in the spleen and Cobra Venom Factor (CVF), sometimes referred to as C3b (Cobra), is the non-toxic, complement-activating component of cobra venom. Like naturally occurring human C3b, CVF forms a complex, or convertase, with complement components Factor B and Factor D. Polymorphisms in the complement receptor 1 (CR1) gene are associated with response to eculizumab.
