Sepharose 16-23 complement C3 Homo sapiens 47-50 2953614-8 1987 C3b purified by anion-exchange fast protein liquid chromatography on a Mono Q column or eluted from a monoclonal anti-C3b-Sepharose retained its modulating activity, while native C3 or C3 fragments such as iC3b, C3c or C3d,g were ineffective. Sepharose 122-131 complement C3 Homo sapiens 0-3 2953614-8 1987 C3b purified by anion-exchange fast protein liquid chromatography on a Mono Q column or eluted from a monoclonal anti-C3b-Sepharose retained its modulating activity, while native C3 or C3 fragments such as iC3b, C3c or C3d,g were ineffective. Sepharose 122-131 complement C3 Homo sapiens 118-121 3952470-4 1986 By using antihuman C3 antibodies, trypsin treatment, and sodium dodecyl sulphate washing, we were able to demonstrate C3b and iC3b on the agarose beads. Sepharose 138-145 complement C3 Homo sapiens 118-121 3488995-7 1986 When C3 was cleaved with trypsin, C3b and C3d but not C3c bound to laminin-Sepharose. Sepharose 75-84 complement C3 Homo sapiens 34-37 3952470-6 1986 We conclude that in vitro human monocytes produce and secrete the essential factors for activation and propagation of the alternative complement pathway (factors C3, B, D, H and I), which becomes evident with an external activator like agarose beads in the cultures. Sepharose 236-243 complement C3 Homo sapiens 162-179 3952470-7 1986 The activation of complement by agarose beads results in the attachment of C3b and iC3b to the surface of the beads, which are then phagocytosed by means of C3b and iC3b receptors on the monocytes. Sepharose 32-39 complement C3 Homo sapiens 75-78 3952470-7 1986 The activation of complement by agarose beads results in the attachment of C3b and iC3b to the surface of the beads, which are then phagocytosed by means of C3b and iC3b receptors on the monocytes.

Sepharose 105-112 complement C3 Homo sapiens 41-58 6379853-6 1984 Since agarose beads are activators of the alternative pathway of complement, and fibronectin is reported to bind to factor C3, we speculate that cell-derived C3b is bound to the beads and fibronectin-coated beads are ingested by the phagocytes via complement C3b receptors on the cells.
