The monoclonal antibody 7G1 recognizes human M-ficolin, also known as ficolin-1. Ficolins are a family of pattern recognition molecules containing both a collagen-like domain and a fibrinogen-like domain that are capable of activating the complement system, through association with MASPs, on the surface of microorganisms. In human, three Ficolins are known: M-Ficolin, L- Ficolin (Ficolin-2), and H-Ficolin (Ficolin-3). M-Ficolin, is mainly expressed by- monocytes, granulocytes and- lung cells and is present locally in areas of inflammation. However, it was recently also found in serum suggesting that M-Ficolin also has a role in systemic immunity like L- and H-Ficolin. Functional analysis of M-Ficolin has demonstrated that it’s ligand is sialic acid present on bacteria since binding was abolished by prior treatment of the bacteria with sialidase. Furthermore, it was shown that M-ficolin facilitates the uptake of E. coli- by a leukemic monocyte lymphoma cell line, suggesting that it functions as a phagocytic receptor on the surface of circulating monocytes. Low cord blood concentration of M-ficolin has been- associated with higher necrotizing enterocolitis-associated fatality and two identified SNPs in the M-ficolin gene are associated with the development of rheumatoid arthritis. The monoclonal antibody 7G1 is suitable for use in immunoassays and western blotting. –
Flow cytometry, Immuno assays, Western blot
For Immuno assays and Western blotting, dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50. For functional studies, in vitro dilutions have to be optimized in user's experimental setting.
