A new transferrin allele in sheep

An electrophoretic variant of sheep transferrin, TfL, has been described. Transferrin L has been shown to be controlled by a single codominant allele, TfL, at the Tf locus. Transferrin L is electrophoretically distinguishable from the very similar transferrin TfKCzech. The value of gradient polyacrylamide gel electrophoresis for transferrin phenotyping in sheep is discussed.
