The SOD levels in rat testicular tissue were measured using a colorimetric SOD activity assay kit (Sigma-Aldrich, Darmstadt, Germany) at a wavelength of 550 nm [18 (link)]. Blood samples were collected from the aortic arch to obtain serum for measuring the MDA and testosterone levels. The MDA levels in serum were measured using the thiobarbituric acid-reactive substance (Sigma-Aldrich) method with an ultraviolet-1601 spectrophotometer at a maximum wavelength of 535 nm [19 ]. Serum testosterone was measured using a solid-phase competitive chemiluminescence enzyme immunoassay with a testosterone kit (IMMULITE® 1000 total testosterone, Siemens AG, Munich, Germany) [20 (link)].

Superoxide Generation and SOD Activity

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells in 96-well plates were refed before treatment with 100 μL of a 70% Hank's Buffered Solution/30% RPMI mix to limit potential antioxidant effects of complete medium. A superoxide generating hypoxanthine (X) and xanthine oxidase (XO) (1.0 mU/mL) combination was added to cells and L3000/SOD3 complexes were added after 1 h. Supernatant was collected after 48 h and SOD activity assessed using a colorimetric SOD activity assay kit (Sigma-Aldrich) (n = 3).

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.
