C4d complement

Lymph node, C4d complement (A24-T)

Host: Rabbit

Application: IHC-P

Species reactivity: Human. Others not tested.

Description: This antibody recognizes human complement component 4d (C4d). Activation of the classical complement pathway begins with binding of an activating substance to the C1 molecule, which activates the C1 sub-units, resulting in cleavage of C4 to C4b releasing C4a in the process. The short-lived C4b molecule can bind covalently to membranes. This process is limited to the immediate vicinity of the C1 complex. Because of the short life of the C4b molecule much of the C4d is free and circulates in serum.
