fFN (Fetal Fibronectin) Test Kit

Fetal fibronectin(fFn) is secreted by amnion, decidua, and chorion. It exists in glycosidoprotein between the decidua and chorion, playing a role in the adhesion to the caul. After the pregnant for 21 weeks, the release of fFn is prevented by the integration of chorion and decidua. Therefore, when the normal pregnant women are at their 22 to 35 weeks of gestation, the content of fFn is very low. When the chorion separates with decidua, the extracellular matrix on the interface of both chorion and decidua are damaged by mechanical damage, and the proteolytic enzymes degradate, the fFN leaks into the secretion of the posterior fornix. The level of fFN in cervicovaginal secretions during 22 to 35 weeks of pregnancy have a good correlation with the premature labor.

Diagnostic kit for fetal fibronectin( Colloidal gold) adopts the principle of double antibody sandwich method and colloidal gold immune chromatography.
