Abstract:
Human serum 8-hydroxy-2'-deoxyguanosine (8-OHdG) was measured by HPLC-ECD method combined with solid phase extraction (SPE) developed by our group: (our proprietary kit, named 8-OHdG Pre-treatment Kit (TANITA Corporation)). The major interfering substances and proteins in serum were removed by 8-OHdG Pre-treatment Kit. This measurement method was highly reproducible (CV=2.2-7.1%) and demonstrated the lower detection limit for control serum sample of less than 10 pg/ml without the sample evaporation. The other hand 8-OHdG concentration in serum for healthy people was in the range of 0-70 pg/ml (25.5+/-13.8 pg/ml, n=37). Secondary a relationship between the HPLC-ECD and ELISA methods was investigated. ELISA method could not detect 8-OHdG concentration in serum for healthy people, because the detection limit of 130 pg/ml was higher than the normal range for healthy people. These results show our SPE method has high sensitivity and quantitative accuracy for 8-OHdG analysis.
