| Abstract: | Blood samples were taken from individual meadow voles (Microtus pennsylvanicus) and white-footed mice (Peromyscus leucopus) every three weeks. Two serum proteins, albumin and transferrin, were examined using acrylamide electrophoresis and densitometry. In individuals of both species, electrophoretic mobility and banding pattern changed. Such changes have been documented in other proteins, and may reflect changes in the internal or external environment of the individuals. Individual changes in serum proteins may seriously affect their interpretation, when used as genetic markers in population studies. |
