Paper Electrophoretic Patterns of Human Serum Proteins Compared with Those of Lower Forms.∗

The paper electrophoretic pattern of human serum has a general resemblance to other mammalian species in number of components and their electrophoretic properties. Globulin and albumin fractions of avian species (domestic fowl, cormorant) resemble in mobility those of the human. Serum components of lower vertebrates differed in their electrophoretic properties from those of the human and thus are not comparable. The serum pattern from an anthropod, H. americanus, was completely different from the patterns obtained from vertebrates.
