MALATE DEHYDROGENASE: MULTIPLE FORMS IN SEPARATED BLASTOMERES OF SEA URCHIN EMBRYOS.
Sea urchin embryos at the 64-cell stage were dissociated by treatment with trypsin and separated by centrifugation on a sucrose gradient. The large blastomeres have two and the small blastomeres have three bands of L-malate dehydrogenase activity, which are separated by disk microelectrophoresis on polyacrylamide gel, whereas unfertilized eggs have five.
