Preparation of monoclonal antibodies to C3b by immunization with C3b(i)-Sepharose

Journal of Immunological Methods, 1989
We have prepared and characterized four monoclonal antibodies (MAbs) to human C3b of high specificity and affinity. Our procedure did not require a purified source of C3b for immunization. Instead, C3b and C3bi were deposited on Sepharose 4B via the alternative pathway of complement activation in normal human serum, and this C3b(i)-Sepharose served as ...

Activated C3 (C3b) in the nephritic glomerulus

Pediatric Nephrology, 1993
An autoradiographic technique was developed to assess in the nephritic glomerulus the relative amount of C3 which is in the activated form, C3b, compared with the inactivated form, iC3b. Frozen renal biopsy sections from children and young adults with glomerulonephritis were assessed for the C3b fraction of total C3, using a radiolabeled monoclonal ...

Mechanism of action of the C3b inactivator: Requiremen for a high molecular weight cofactor (C3b-C4bINA cofactor) and production of a new C3b derivative (C3b′)

Immunochemistry, 1977
Abstract We investigated the mechanism of cleavage of human C3b by the C3bINA and documented the polypeptide chain structure of the breakdown products. As reportd for C4b cleavage by C4bINA (Shiraishi & Stroud, 1975; Nagasawa et al., 1976), the C3bINA requires a macromolecular protein for limited proteolysis of C3b.

Degradation of C3b by the C3b Inactivator

The Journal of Immunology, 1971
Abstract The C3b Inactivator (C3bINA) is a normal serum β globulin which destroys the activity of cell-bound C3b in immune hemolysis, immune adherence and the enhancement of phagocytosis. C3bINA treatment of EAC14oxy23 prepared with 125I-labeled C3 releases protein-bound radioactivity into the supernatant fluid.
