Image caption:
In vivo C3 binding on red cells of PNH patients on eculizumab. a Kinetics of C3 binding on red cells from a representative PNH patient during eculizumab treatment. Before treatment (0 week), no red cell binds C3, whereas starting from 1 week of treatment three populations of red cells are displayed: one population of normal red cells (CD59 + C3−) and two distinct populations of PNH (CD59-negative) red cells, one with (C3+) and one without (C3−) fragments bound on their surface. b Characterization of C3 fragment bound to erythrocytes from PNH patient on eculizumab. The left panel shows the normal (CD59-positive) and PNH (CD59-negative) populations (gated by the elliptic mark). The PNH (CD59-negative) population (see gate in the left panel) has been analyzed with anti-C3d and either anti-C3b (middle panel) or anti-iC3b (left panel). SSC: side scatter

Mouse anti Human C3b antibody, clone H11 recognizes human C3b, part of the complement system. C3 is cleaved by C3-convertase creating C3a and C3b, which binds to the surface of pathogens leading to their destruction by phagocytic cells. Mouse anti Human C3b antibody, clone H11 recognizes a determinant present on native (circulating) C3 and on the fragments C3b and C3c. The antibody is directed to a determinant present on the betachain of the C3 molecule (Western blot). It does not react with the anaphylatoxin C3a or the fragment C3d and does not inhibit the haemolytic function of C3.
