TCC ELISA, human, kit

Harnessing the power of the complement system, the Terminal Complement Complex (TCC),
also known as the Membrane Attack Complex (MAC), stands as a crucial player in our body’s
defense mechanism. When the classical, lectin, and alternative pathways unite, they give rise
to the C5 convertase, which sets the stage for the TCC’s formation. Unlike earlier stages that
depend on enzymatic action, the TCC forms through a cascade of conformational shifts,
beginning with C6 and culminating in the pivotal C7 binding, which fundamentally changes the
complex’s structure.
The TCC is characterized by unique neoantigens, distinct markers that emerge in both the
cellular MAC and the fluid-phase SC5b-9 complex. These markers are absent in the individual
native components, marking the TCC’s presence as a sign of active complement engagement.
Typically, TCC levels in human plasma are negligible, yet an increase signals an immune
response, offering a window into the system’s response to pathogenic threats. By monitoring
TCC levels, we gain invaluable insights into immune system activity, providing a strategic
advantage in both diagnostic and therapeutic realms.

How to analyze complement

For accurate complement analysis, it is important that not only the correct technique is used but also that pre-analytical sample handling is performed in an appropriate manner to avoid erroneous results.
