Electrophoretic analysis of blood of Tilapia leucosticta Trewavas and Tilapia zillii (Gervais) from Lake Victoria

Zone electropho~esis is one of the most useful tools now available for the separation of proteins in tissue fluids of organisms; it allows· the examination of the variability of specific proteins among taxa and the comparison of proteins of one organism with another. In recent years there has been a marked increase in the applic'ation of electrophoretic techniques to taxonomic problems which has demonstrated that the .comparison of proteins can add to more traditional criteria a sensitive means of characterizing taxonomic groups at all levels and of elucidating relationships between the
