Abstract
Summary
A ratio of 3 volumes 0.4% rivanol to one volume serum was used to partially purify cattle transferrin. After treatment, the supernatant fraction contained predominantly transferrin and γ-globulin. No albumin was detectable by starch gel or paper electrophoresis. Fractionation of serum from cattle of phenotypically different transferrin types yielded transferrin with the same pattern and mobility in starch gel electrophoresis as in the original serum.
