Lactoferrin concentration in human parotid saliva as measured by an enzyme-linked immunosorbent assay (ELISA)

The enzyme-linked immunosorbent assay (ELISA) was found to be a reliable and accurate method for quantitating lactoferrin in parotid fluid. In saliva from normal glands, the concentration was usually below 1 mg% and was always higher in unstimulated than in stimulated secretion.
