We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

SERPING1 also known as C1 inhibitor or C1-inactivator is a protein that plays an important mechanical role in the regulation of the complement system. It is a member of the serpin superfamily and has a molecular mass of approximately 105-110 kDa. This protein is mainly expressed in the liver but also present in other tissues such as monocytes and epithelial cells. As an inhibitor SERPING1 effectively regulates the activity of the complement subcomponents C1r and C1s plasmin and kallikrein by inhibiting their protease activity preventing unwanted activation of the complement cascade.
Biological function summary

The protein acts as a critical control point in the complement and contact activation system. It is part of the C1 complex which includes the proteins C1q C1r and C1s. The regulation extends to pathways that involve the breakdown of plasma proteins and prevention of spontaneous inflammatory reactions. By controlling these pathways the protein prevents excessive inflammation and tissue damage which can occur during immune responses. Its involvement extends to the regulation of the complement system and maintenance of vascular permeability.

Pathways

SERPING1 interacts closely with mechanisms involved in the complement cascade and the kinin-kallikrein pathways. It associates with proteins like MASP-1 and MASP-2 important in the complement and lectin pathways. These pathways are important for innate immunity and influence factors like inflammation and blood pressure. SERPING1 modulates these pathways by inhibiting key enzymes and ensuring controlled responses therefore maintaining systemic balance within the immune system.

The malfunction or deficiency of SERPING1 has direct links to hereditary angioedema a condition marked by severe and rapid swelling episodes. The disorder results from inadequate inhibition of bradykinin emphasizing the protein's role in vascular regulation. Additionally the protein has implications in autoimmune diseases such as systemic lupus erythematosus where complement regulation is disrupted. The interplay between SERPING1 and other proteins such as bradykinin receptor B2 remains significant in understanding disease mechanisms and developing therapeutic interventions.

Target data

Activation of the C1 complex is under control of the C1-inhibitor. It forms a proteolytically inactive stoichiometric complex with the C1r or C1s proteases. May play a potentially crucial role in regulating important physiological pathways including complement activation, blood coagulation, fibrinolysis and the generation of kinins. Very efficient inhibitor of FXIIa. Inhibits chymotrypsin and kallikrein.
