Determination of effect of TSCE-W on generation of lipid peroxidation in CCD-1064Sk cells —
The assay was evaluated by using thiobarbituric acid reactive substances assay according to the slightly
modified method of Chirdchupunseree and Pramyothin.
The cells were seeded at a density of 1× 105 cells/mL in a 6-well plate for 24 h. After themedium was removed, the cells were added with TSCE-W at various concentrations for 24 h.
The cells were washed twice with 1 mL of cold PBS and then lysed on ice with 300 of 2% SDS for 30 min.
Cell lysate was transferred into a glass tube and adjusted to 1 mL with 2% SDS.
A volume of 3 mL of the reaction mixture contained 950 of the cell lysate, 50 of
4% BHT, 1 mL of 10% phosphotungstic acid, and 1 mL of 0.7% TBA. The mixture was mixed and heated at 100 for 1 h, cooled and added 4 mL of n-butanol, centrifuged at 3600 rpm for 10 min.
The supernatant was measured by using a spectrofluorometer with an excitation wavelength at 515 nm and an
emission wavelength at 553 nm.
MDA level was calculated from a standard curve of TEP.
The results were expressed as nmol MDA/mg protein.
Protein content was determined by Bradford method26.
