Fetal fibronectin (fFN) is used to test pregnant women who are between 22 weeks and 35 weeks of gestation and are having symptoms of premature labor. The test helps predict the likelihood of premature delivery. Many pregnant women experience symptoms that suggest preterm labor.
Fibronectin is a high-molecular weight (~440kDa) glycoprotein of the extracellular matrix that binds to membrane-spanning receptor proteins called integrins. Similar to integrins, fibronectin binds extracellular matrix components such as collagen, fibrin, and heparan sulfate proteoglycans (e.g. syndecans). Fibronectin exists as a protein dimer, consisting of two nearly identical monomers linked by a pair of disulfide bonds. The fibronectin protein is produced from a single gene, but alternative splicing of its pre-mRNA leads to the creation of several isoforms. Two types of fibronectin are present in vertebrates: 1  soluble plasma fibronectin (formerly called cold-insoluble globulin, or CIg) is a major protein component of blood plasma (300 Î¼g/ml) and is produced in the liver by hepatocytes.  insoluble cellular fibronectin is a major component of the extracellular matrix.
