Xanthine oxidase, hypoxanthine, and polypyrrole (PPy) were obtained from Sigma-Aldrich (St. Louis, MO). Blocker Casein in phosphate buffered saline (PBS) buffer and Blocker BSA (bovine serum albumin; 10%) in PBS and Dulbecco's PBS (DPBS) buffer were purchased from Thermo Scientific (Tustin, CA). Deionized (DI) water was generated using a Barnstead Smart2Pure water purification system (Barnstead, Van Nuys, CA). Xanthine oxidase was resolved using 10% BSA in PBS and serially diluted in PBS buffer. All remaining biochemicals were used without further purification.
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.
