Abstract
Two hæmoglobin components have been demonstrated by starch gel electrophoresis in both larval and adult forms of Petromyzon planeri 1. Although the components are most clearly separated by electrophoresis in starch gel, separation has also been obtained by starch block electrophoresis and on acetate cellulose paper. Furthermore, after elution of the individual bands it was found that each one then runs as a single component in the starch gel system (Fig. 1). It seems therefore quite likely that the separation in the different hæmoglobin bands is due to differences in molecular size. Concerning the electrophoretic mobility of these hæmoglobins as compared to human ones it must be noted that their isoelectric point, unlike that of other species of lampreys2, seems to be in the region of neutrality.
