SEE ALSO...

C1INH Antibody (B-11) is a mouse monoclonal IgG1 kappa light chain antibody that detects C1INH protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). C1INH (B-11) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. C1INH protein, also known as plasma protease C1 inhibitor, plays a critical role in regulating the complement and contact activation pathways, which are essential for maintaining homeostasis in the immune response. By inhibiting serine proteases such as C1r and C1s, C1INH prevents excessive inflammation and tissue damage, making C1INH vital for controlling the body′s response to injury and infection. Dysregulation of C1INH can lead to conditions such as hereditary angioedema, characterized by recurrent episodes of severe swelling, highlighting the importance of C1INH in both health and disease. Anti-C1INH antibody (B-11) is an invaluable tool for researchers studying the mechanisms of immune regulation and the pathophysiology of related disorders.

I am planning to use C1INH (B-11): sc-377062 to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Asked by: TinTin
We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
