204860 Complement C3b, Human

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) o SDS, certificato d’analisi (CoA) e certificato di qualità (CoQ), dossier, brochure e altri documenti disponibili.

      Description
      OverviewNative, human C3b complement component. Cleavage of the C3-α chain at peptide bond 77 by either of the complement C3 convertase enzymes results in production of C3a (M.W. 9083) and C3b (M.W. 180,000) fragments. The C3b fragment is a glycoprotein composed of the modified C3-α chain (α′) (M.W. 105,000) and the intact C3-β chain (M.W. 75,000). Nascent C3b has the transient ability to form a covalent ester bond with a variety of target surfaces. Once bound to target surfaces C3b becomes an essential subunit of both the classical and alternative pathway C5 cleaving enzymes. In addition, surface-bound C3b has opsonic and immune adherence activities which are mediated via binding to CR1 (CD35) complement receptors.

      DescriptionNative, human C3b complement component. Cleavage of the C3-α chain at peptide bond 77 by either of the complement C3 convertase enzymes results in production of C3a (M.W. 9083) and C3b (M.W. 180,000) fragments. The C3b fragment is a glycoprotein composed of the modified C3-α chain (α') (M.W. 105,000) and the intact C3-β chain (M.W. 75,000). Nascent C3b has the transient ability to form a covalent ester bond with a variety of target surfaces. Once bound to target surfaces C3b becomes an essential subunit of both the classical and alternative pathway C5 cleaving enzymes.
