Table 1
Methods for preparation of liver biopsy implemented in different studies.
Tissue preparation
Buffer used
Homogenization
Oxidative stress marker
Reference
Tris-HCL (50 mM) pH 7.5
The liver biopsy was homogenized in 20 volumes of cold buffer, and then the supernatant was harvested after centrifugation at 5000 g for 30 min at 4°C.
Liver biopsy was homogenized in chilled buffer. The homogenates were centrifuged at 800 g for 5 min at 4°C to separate the nuclear debris. The obtained supernatant was recentrifuged at 10,500 g for 20 min at 4°C to get the postmitochondrial supernatant.
The tissue was homogenized in 5 ml/g cold buffer. The homogenate was centrifuged at 10,000 g for 15 minutes at 4°C. The supernatant was removed for assay.
