C3b/ic3b
WebThe 3E7 monoclonal antibody specifically recognizes multifunctional C3b and iC3b fragments of the ~190 kDa plasma glycoprotein, Complement component 3 (C3). C3 is a key component of the classical, alternative and lectin complement activation pathways which participate in innate and adaptive immune responses to eliminate pathogens, dying cells, … WebC3b serves as an opsonizing agent, and can be further cleaved by Factor I into C3c and C3d. iC3b is a proteolytically inactive C3b fragment that still opsonizes target microbes or cells, but cannot further amplify/activate the complement cascade through APC. iC3b can be further cleaved to C3dg, and finally to C3d.

WebC3b is involved in all three complement pathways and is essential for effective complement activation and presentation of antigens to cells of the adaptive immune system. iC3b is less active than C3b, but the target-bound protein can expand target-specific B-cell and T-cell populations by interacting with lymphoid and phagocytic cells.

C3 is a key component of the classical, alternative and lectin complement activation pathways which participate in innate and adaptive immune responses to eliminate pathogens, dying cells, … WebC3b is gradually converted to iC3b. iC3b binds only weakly to CR1, but binds strongly to CR3 and CR4, which are found on phagocytic cells. When the red blood cells pass through the liver and spleen, the coated particles are ingested and destroyed by the phagocytotic cells. iC3b is therefore the most effective opsonin of the complement system.
WebC3b-coated particles in the blood mainly bind to red blood cells, which have the receptor CR1 that binds C3b. C3b is gradually converted to iC3b. iC3b binds only weakly to CR1, …
WebC3b is rapidly split in two positions by factor I and a cofactor to form iC3b (inactivated C3b) and C3f which is released. Then iC3b is slowly cleaved (possibly by factor I) to form C3c (beta chain + alpha' chain fragment 1 + alpha' chain fragment 2), C3dg and C3f. Other proteases produce other fragments such as C3d or C3g. dog suddenly started drinking a lot of waterWebThe 3E7 monoclonal antibody specifically recognizes multifunctional C3b and iC3b fragments of the ~190 kDa plasma glycoprotein, Complement component 3 (C3).
