Hepatic Oxidative Stress Biomarkers Quantification

Check if the same lab product or an alternative is used in the 5 most similar protocols
Hepatic levels of malondialdehyde (MDA), a marker of lipid peroxidation, were determined by a thiobarbituric acid method using MDA kit (Biodiagnostic, Egypt). The formed colored thiobarbituric acid reactive product was measured spectrophotometrically at 534 nm (Gavino et al., 1981 (link)). Hepatic glutathione (GSH) levels were measured by GSH kit (Biodiagnostic, Egypt) based on the reduction of 5,5‘dithiobis (2-nitrobenzoic acid) by GSH. The absorbance of colored product was measured at 405 nm (Beutler, 1963 (link)). Aliquots of liver homogenate were used for determination of nuclear Nrf-2, GSK-3β and PI3K levels using rat-specific ELISA kits provided by Wuhan Fine Biological Technology Co., China (catalog no.: ER911, ER0124 and ER1531, respectively). Hepatic levels of HO-1 were estimated by rat-specific ELISA kit supplied by Elabscience Biotechnology Inc., USA (catalog no.: E-EL-R0864) while hepatic rat pAkt concentrations were measured by Cusabio® ELISA kit (China). The Pierce™ bicinchoninic acid (BCA) assay kit supplied by ThermoFisher Scientific, USA (catalog no.: 23227) was used to determine total protein content (Smith et al., 1985 (link)). Tissue parameters were expressed per mg of protein.

Colorimetric Assay for GSH Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
GSH brain levels were assayed using GSH kit of Biodiagnostic, Egypt. The method, according to Beutler and Kelly, depends on the reduction of 5,5’-dithiobis-(2-nitrobenzoic acid) (DTNB) by the SH group in glutathione (GSH) to produce an intense yellow compound. The reduced chromogen is directly proportional to GSH concentration and its absorbance can be measured colorimetrically at 405 nm [81 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
