For protection of cells, antioxidant enzymes such as catalase (CAT), glutathione reductase (GR), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione (GSH) and glutathione-S-transferase (GST) play a vital role in reducing the oxidative stress (Tripathi et al.
A study by DiSilvestro, et al (9) demonstrated that Albion's Selenium Glycinate Complex significantly raised serum glutathione peroxidase activity, which plays a critical role in protecting the central nervous system and asserting a positive impact on cognitive function.
Peroxidase activity was measured according to Vetter et al.
Ascorbic acid peroxidase (APX) activities were assessed by using Nakano and Asada (1987) method
2008), and then analysed for total soluble proteins (Bradford, 1976) and the enzymes catalase (Berrs & Sizer 1952), ascorbate peroxidase (Nakano & Asada, 1981), polyphenoloxidase (Kar & Mishra, 1976) and peroxidase (Fatibelho Filho & Vieira, 2002).
Reagent and procedure used in these procedures using the Horseradish peroxidase (HRP), the Peroxidase-anti-peroxidase (PAP), the Avidin-biotin complex (ABC), or the Alkaline phosphatase-anti-alkaline-phosphatase (APAAP) for detection of antigen-specific antibodies in frozen or paraffin sections are necessary for the validation of the staining results.
In order to assaying of protein content and catalase, Peroxidase and superoxid dismutase activities, fruits tissue of each treated and control samples (0.
Ascorbate peroxidase is a main enzyme involved in detoxification of [H.
The enzyme-free detection system is based on the electrochemical properties of Fe 3O4 nanoparticles, which have been known to mimic the peroxide-reducing capacity of horseradish peroxidase.
