It has been suggested that information on the phylogenetic relationships of genera and species could be obtained by comparing the amino acid sequence in the homologous proteins of different species. This procedure is extremely difficult and time-consuming.
However, a relatively rapid characterization of proteins can be obtained by analysing their mobilities with starch-gel electrophoresis and examination of antigenic diversity by the agar gel diffusion technique of Ouchterlony.
