Rapid Determination of Fibronectin by Laser Nephelometry Fibronectin concentrations in plasma in human diseases, I.

Abstract
Fibronectin (cold-insoluble globulin, antigelatin factor) is a cell surface glycoprotein. Remarkably large amounts of fibronectin are present in human plasma. Owing to the difficulty and expensiveness of radioimmunoassays, only a few reports on the relation of fibronectin and human diseases have so far been published. A rapid and easily handled immunoassay, using the light scattering effect, is described. The measurement of fibronectin concentrations in the plasma of patients with chronic active liver diseases are reported.
