C2

The protein corresponding to the gene C2 is Complement C2. It is also commonly known as C2 complement protein. Complement C2 plays a crucial role in the classical and lectin pathways of the complement system. It is cleaved to form part of the C3 and C5 convertases, which are key enzymes in the activation cascade. This activation leads to a series of immune responses such as opsonization and cell lysis.
Dysregulation of Complement C2 is associated with various diseases, including certain autoimmune disorders and susceptibility to infections. In drug development, targeting Complement C2 is being explored as a potential strategy to modulate the complement - mediated immune response, although significant challenges remain in developing effective and safe drugs.

The following C2 reagents supplied by CUSABIO are manufactured under a strict quality control system. Multiple applications have been validated and solid technical support is offered.
