| complement 8 | The next to the last essential component for cell lysis in the complement reaction sequence. It is a gamma-globulin with a molecular weight of 150,000 and a sedimentation coefficient of 8. It is present in trace amounts in serum and can be inhibited, like complement 1, by cation chelators. (12 Dec 1998) |
|---|---|
| complement 9 | The last component in the complement reaction sequence. It is an alpha-globulin present in serum as a trace, with a molecular weight of 80,000 and a sedimentation coefficient of 4.5. For cell lysis, it can be replaced by a metal chelator. (12 Dec 1998) |
| complement activating enzymes | <enzyme> Enzymes present in the complement system which activate one or more components in the system. Registry number: EC 3.- (12 Dec 1998) |
| complement activation | The sequential activation of serum components c1 through c9, initiated by an erythrocyte-antibody complex or by microbial polysaccharides and properdin, and producing an inflammatory response. (12 Dec 1998) |
| complement binding assay | A test for the detection of immune complexes. (05 Mar 2000) |
| complement chemotactic factor | The activated complex of the fifth, sixth, and seventh components of complement (C567) which induces chemotaxis in the case of polymorphonuclear leukocytes. (05 Mar 2000) |
| complement cytolysis inhibitor | <protein> Vertebrate glycoprotein of uncertain function. Secreted as a 400 amino acid peptide, then cleaved to form two 200 amino acid peptides that are linked by a disulphide bridge. Synonym: complement associated protein, complement cytolysis inhibitor, glycoprotein III. (11 Jan 1998) |
| complement factor h | <chemical> A beta-globulin that binds to complement 3b and makes ic3b (inactivated complement 3b) susceptible to cleavage by complement factor I. Complement factor h also acts as an alternative pathway complement inhibitor by interfering with the binding of properdin factor b to c3b. Chemical name: Complement factor H (12 Dec 1998) |
| complement factor I | <enzyme> Serine proteinase that acts on ic3b (inactivated complement 3b) to cleave it into c3c and c3dg with the help of a trypsin-like proteolytic enzyme. Complement factor I was formerly called kaf, c3binf, or enzyme 3b inactivator. Registry number: EC 3.4.21.45 (12 Dec 1998) |
| complement-fixing antibody | Antibody that combines with and sensitises antigen leading to the activation of complement, which may result in cell lysis. Synonym: CF antibody, sensitizing substance. (05 Mar 2000) |
| complement haemolytic activity assay | Usual screening assay for complement. Dilutions of the serum to be tested are added to antibody-coated erythrocytes and the percentage of lysis is measured. The values are expressed by ch50, haemolytic complement units per milliliter, which is the dilution of serum required to lyse 50 percent of the erythrocytes in the assay. (12 Dec 1998) |
| complement inactivators | Serum proteins which act at key sites in the complement sequence to modulate or prevent the progression of the reaction. Absence of these factors leads to uncontrolled activation of the complement system with accompanying disease. (12 Dec 1998) |
| complement membrane attack complex | The assembly of complement plasma glycoproteins c5b, c6, c7, c8, and polymeric c9 as a group on biological membranes. The complex forms transmembrane channels which displace lipid molecules and other constituents, thus disrupting the phospholipid bilayer of target cells leading to cell lysis by osmotic leakage. The formation of the membrane attack complex is the terminal step in the complement cascade. (12 Dec 1998) |
| complement pathway, alternative | The complement activation sequence initiated by the activation of complement factor c3, which is triggered by the interaction of microbial polysaccharides and properdin without participation of an antigen-antibody reaction. (12 Dec 1998) |
| complement pathway, classical | The sequential activation of complement, initiated by antigen-antibody complex and the binding of complement factor c1q to the fc region of the antibody. (12 Dec 1998) |
