The microheterogeneity of human transferrins in biological fluids.
The serum, cerebrospinal fluid, amniotic fluid and synovial fluid transferrins have been examined by isoelectric focusing in a pH gradient from 5-7. In all biological fluids the presence of transferrins with a varying content of sialic acid has been shown. Differences between the fluids with regard to transferrin have been noticed.
