Experiment Condition
95% N2: 5% H2 gas mix 99.995% using pure gases
Equipped with a Pd catalyst at 20~25oC
Solutions were purged with O2-free N2
and stored in the chamber for least 5 days.
0.25M Fe(Ⅱ) and other samples were prepared inside the chamber and using material for at least 5 days .
Stock Fe(Ⅱ) solutions were stored at pH<1.0 in amber containers wrapped with aluminum foil
aluminum foil로 뚜껑을 하여 dessicator안에서 보관하여 식힌 후 lipid의 무게를 재었다. 그리고 이것을 일정량의 CHCl3 로 녹여 TLC로 lipid fraction하였다.
