Human C3 ELISA Kit

Complement C3 is a protein that plays a crucial role in the immune system as part of the complement system. The complement system is a complex network of proteins that work together to enhance the immune response against pathogens such as bacteria and viruses. Complement C3 is one of the central components of this system.

When the complement system is activated, C3 is cleaved into two fragments: C3a and C3b. C3b plays a key role in opsonization, a process in which pathogens are marked for destruction by phagocytic cells, such as macrophages. Additionally, C3b participates in the formation of the membrane attack complex (MAC), which can directly lyse and kill certain pathogens.

The complement system is an essential part of the immune defense mechanism, contributing to the body's ability to recognize and eliminate foreign invaders. Dysregulation of the complement system has been associated with various autoimmune diseases and inflammatory conditions.
