for each space , the same value was obtained when centrifugal filtration was done at 8000 and at 15,600 g , and when the mitochondria were incubated with the markers for 15 s to 5 min , indicating that sucrose , mannitol and inulin do not penetrate the matrix , nor does dextran penetrate the intermembrane space , under the incubation and centrifugation conditions generally used to measure mitochondrial spaces .
