Conjugation ready
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

Sandwich ELISA
The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody in your assay.

Supplementary information

C1 inhibitor also known as C1 esterase inhibitor or C1-INH is a serpin family protein that plays a significant role in inhibiting the complement system. This protein found in human serum has a molecular mass of about 104 kDa. C1 inhibitor is predominantly expressed in the liver and secreted into the bloodstream where it functions to regulate several proteolytic cascades. As a glycoprotein it also contains significant carbohydrate moieties that aid in its stability and function.

Biological function summary

As an inhibitor of the classical pathway of the complement system C1 inhibitor controls the activation of C1 esterase. This interaction prevents the uncontrolled activation of downstream components of the complement cascade which could result in tissue damage. C1 inhibitor also participates in regulating the kallikrein-kinin system preventing excessive inflammation. It achieves these roles not alone but as a part of complexes that interact with other proteins to maintain homeostasis within the immune system.

Pathways

The role of C1 inhibitor intersects with critical inflammatory modulatory pathways such as the complement pathway and the kallikrein-kinin system. These pathways are essential for proper immune response modulation preventing excessive inflammation and maintaining vascular permeability. C1-INH acts alongside proteases like kallikrein and proteins like C4 and C2 within these pathways to regulate the initiation and progression of the immune response during infections or insults.

Inadequate levels or functional defects in C1 inhibitor lead to hereditary angioedema a condition characterized by recurrent episodes of severe swelling. This disease highlights the importance of C1-INH in controlling vascular leakage and inflammation. Moreover C1 inhibitor has been implicated in autoimmune diseases like systemic lupus erythematosus where its regulatory kinetics with proteins such as C1q play a part in managing excessive complement activation. These associations highlight the important protective role of C1 inhibitor in health and disease.

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.
