Abstract
Immunoglobulins [Ig] in whole saliva, collected unstimulated from 60 healthy children, 4-15 yr of age, were determined by a modified electroimmuno technique using carbamylation of the samples prior to electrophoresis. This technique, which is generally used for measurement of IG in serum, was rapid, precise and sensitive. The mean (median) for salivary IgA was 5.1 kIU/1, which was significantly higher than values obtained from stimulated or unstimulated parotid saliva by other investigators. The mean value for salivary IgG was 120 IU/l. IgM in saliva was only found in measurable amounts in 5 children.
