Blood-group A and G specific structures in toad (Bufo) spawn. Comparative studies on three species (Bufo bufo, Bufo viridis, Bufo calamita).
Permethylation analyses of the spawn material of three toad (Bufo) species allow the conclusion that the serologically determinant group in Bufo bufo spawn is identical with that found in human and hog blood-group A substances (i.e. GalNAc(alpha1,3) [Fuc(alpha1,2)] Gal -), and the serologically determinant group in Bufo viridis and Bufo calamita spawn is identical with that found in blood-group H substances (i.e. Fuc(alpha1,2) Gal -).
