| Abstract: | The electrophoretic behaviour of arginase in the tissue extracts of rat, beef, lizard and frog was studied by bidirectional polyacrylamide gel electrophoresis. The enzyme from rat liver and submaxillary gland migrated to the cathode with the activity concentrated in a single peak. Arginase from beef liver emerged as a single peak of anodal migration with a significant shoulder in the sample gel. Frog liver and kidney enzymes also appeared as single peaks with a distinct anodal movement. The activity in mammalian kidney and lizard liver and kidney resolved into two peaks of anodal migration suggesting the presence of two isoenzymes of arginase in these tissues. |
