I've tried to isolate mitochondria using a discontinious percoll gradient 
inwhich we use three concentrations of percoll. At the bottom 40%, second a 
23% percoll solution and third the rough mitochondrial preparation in 15% 
percoll. Afther centrifugation for 5 minutes mitochondria are described to 
flow between the 40 and 23% percoll. My interest goes to the very brown 
fraction at the bottom below the 40% percoll. Does anybody know what this 
fraction may consist. It has almost no protein in it. Why is it so brown and 
Please give me your advice as soon as possible
