Tin tetrachloride hydrate (SnCl4·5H2O) and thioacetamide were obtained from Macklin Biochemical Co., Ltd (Shanghai, China). Dicyandiamide, urea and nitric acid were all purchased from Damao Chemical Reagent Factory (Tianjin, China). NHS and EDC were both purchased from Aladdin Reagent Database Inc. (Shanghai, China). Bovine serum albumin (BSA) was purchased from Sigma-Aldrich (Beijing, China). PSA and anti-PSA were both purchased from Shanghai Linc-Bio Science Co., Ltd., China. All other chemicals were analytical grade and used without further purification. Phosphate buffer solution (PBS) is a mixed solution of disodium hydrogen phosphate (Na2HPO4·12H2O, 0.1 mol·L−1) and potassium phosphate monobasic (KH2PO4, 0.1 mol·L−1), which was used for the preparation of the antibody, antigen and washing buffer solution. All aqueous solutions were prepared by using ultrapure water (Milli-Q, Millipore).
Nitric acid
Manufactured by Tianjin Damao
Sourced in China
Nitric acid is a highly corrosive, colorless to yellowish liquid chemical compound. It is primarily used as a reagent in various industrial and laboratory processes. The core function of nitric acid is to act as an oxidizing agent.

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.
