The inhibitory properties of group A and B non-secretor saliva.
The existence of some form of specifically active A or B blood group substance in the saliva of group A1, A2 and B non-secretors was demonstrated. Significant inhibition of agglutination results were obtained when the salivas of these non-secretors were examined in a test procedure using anti-A + B (group O) serum and group AX red cells. Native saliva specimens from group A1, A2 and B secretors and non-secretors were filtered on Sephadex G-200 columns. The eluates were tested for blood group activity by inhibition of agglutination and for relative carbohydrate and protein content. A main excluded glycoprotein, blood group-active fraction was detected in all samples of saliva examined.
