Geographical Distribution of Twelve Transferrin Alleles in Black Rats of Asia and Oceania
About 450 black rats (Rattus rattus) were collected from 25 localities in Asia and Oceania. Their serum transferrins were analyzed by a newly developed thin layer acrylamide gel electrophoresis accompanied with acrinol pretreatment, exhibiting 12 transferrin bands. Generally, Asian type rats (2N=42)...
