Serum fibronectin

Fn is a & alpha; 2 glycoprotein composed of two subunits, which can be divided into two forms: CFn and PFn. One of the main functions is as a transmitter of phagocytosis of macrophages and reticuloendothelial cells, promoting reticuloendothelial cells to fibrin, fibrinogen-fibrin complex, collagen fragments, damaged cell debris, bacteria Conditioning and removal of non-bacterial toxic substances. CFn is a matrix protein of connective tissue, which is distributed with collagen fibers in the liver, and the level is increased during liver fibrosis.
