C5b-9 is also known as the terminal complement complex (TCC). The TCC consists of C5b, C6, C7, C8 and C9 and forms the membrane attack complex (MAC) as well as the non-lytic fluid-phase SC5b-9 complex (with protein S). The MAC forms channels in target cell membranes leading to cell lysis by osmotic leakage. The complexes contain neoantigens that are absent from the individual native components from which they are formed and DIA 011-01 is directed against a neoepitope exposed on C9 when incorporated into the TCC.

Other information
This product is not for further manufacture.
Application 1

DIA 011-01 is well suited for quantifying TCC in ELISA. (2,3)

Application 2

DIA 011-01 is not recommended for Western blotting as the epitope is destroyed during the process (4).

Application 3

TCC in various tissues by immunohistochemistry (frozen and paraffin sections) (1, 2, 4).

IHC staining of frozen tonsil section. Vascular endothelia and dendritic cells of germinal center have strong and intensive label. Dilution: 1:10.


Application 4

DIA 011-01 can be used in immunofluorescence staining (5).
