Ficolin-1 precursor recombinant protein epitope signature tag (PrEST)

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

FCN1 (Ficolin-1) also called as M-ficolin belongs to the ficolin family of proteins. It is mainly expressed in the peripheral blood leukocytes and is suggested to function as a plasma protein with elastin-binding activity. It is a transmembrane C-type lectin that functions as a pattern-recognition receptor in innate immunity. It binds to monocyte transmembrane G protein-coupled receptor 43 (GPCR43) and forms a complex. Upon microbial invasion, this complex activates the NF-κB cascade in immune signaling. Acidosis at the site of infection induces the complex to interact with C-reactive protein (CRP) to form CRP-M-ficolin-GPCR43, which inhibits IL-8 production thus preventing immune overactivation. The protein binds to 9-O-acetylated 2-6-linked sialic acid derivatives. It also binds to various glycans containing sialic acid having a 2-3 linkage.

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
