isozyme analysis of a series of cho electrophoretic mobility shift mutants for mdh2 ( malate dehydrogenase 2 , ec 1.1.1.37 ) revealed that this locus is functionally hemizygous in cho cells , but the locus could not be mapped by conventional approaches because of the similar electrophoretic mobilities of chinese hamster and mouse mdh2 isozymes .
