A transferrin variant migrating faster than Tf A was described by Glasnak et al. (1976). It was found in crosses of wild and domestic pigs. A similar variant was detected in wild pigs by Skladanowska et al. (1977; 1979). They provisionally designated it Tf 4, (Skladanowska et al., 1977) and in a definitive paper Tf P (Skladanowska et al., 1979). Palovics et al. (1982) found a fast-moving trans- ferrin in Large White breed of pigs.

We compared starch gel electrophoretic mobilities of transferrins from these three sources with a discontinuous Tris-citric acid/NaOH-boric acid buffer system according to Kristjansson (1963) (see also Glasnak et al., 1976).

The mobilities of the fastest moving transferrins from these three sources were identical.

We therefore propose to unite the nomenclature and to designate the pig transferrin variant which is slightly faster than Tf A with the symbol Tf I, re- gardless of whether it is found in domestic or wild pigs.
