the following differences between mitochondrial and microsomal protein synthesis in vitro were used to measure selectively the mitochondrial portion in cell fractions sedimenting between 600 and 10000 x g : selective inhibition of mitochondrial protein synthesis by chloramphenicol/thiamphenicol selective inhibition of microsomal protein synthesis by cycloheximide kinetics of amino acid incorporation a medium favoring mitochondrial protein synthesis activity of mitochondrial protein synthesis was based on measurements of cytochrome oxidase , a mitochondrial marker enzyme .
C0008168
chloramphenicol
