The following should help. We isolate mtDNA from sperm and testis biopsy
material by homogenising in SDS lysis buffer (10 mM Tris pH 8.0, 10mM
EDTA, 50 mM NaCl, 2%SDS, 10ulproteinase K (10mg/ml) for 1.5 hours at
56C and purify using Prep A Gene (Bio Rad). Remove tissue by
centrifuging and incubate for 1 hour further at 56C

a technique for monitoring cell ageing and mitochondrial function using
Let me know how you go. What aspect of oxidative damage are you interested in?
