The blueberry anthocyanins were extracted from Rabbiteye blueberries (Lishui Town, Nanjing, China) [53 (link)] and stored at −18 °C at the Institute of Agricultural Products Processing, Chinese Academy of Agricultural Sciences. High-performance liquid chromatography (HPLC) solvents potassium chloride and acetonitrile were acquired from Sinopharm Chemical Reagent Co., Ltd. (Shanghai, China) and TEDIA (Fairfield, OH, USA), respectively. Ferritin (from horse spleen), MOPS buffer, 2,2-bipyridine, and bovine serum protein (BSA) were procured from Sigma-Aldrich (Shanghai, China). The bicinchoninic acid (BCA) and protein-assay kits were purchased from Beijing Solarbio Company (Beijing, China). The reagents used in the experiment are all of analytical grade.

Recombinant toyocamycin nitrile hydratase was expressed and purified as described previously24 (link). Rabbit pyruvate kinase was purchased from Roche; the phosphoglycerate mutase 2 was discovered as a contaminant in that sample. Glyceraldehyde 3-phosphate dehydrogenase was isolated from HeLa S3 cells as described previously25 . Ferritin from horse spleen was purchased from Sigma Aldrich. Finally, human 20S proteasome was purchased from Enzo Life Sciences. All samples were desalted prior to analysis by buffer exchanging with molecular weight cutoff spin filters (Millipore) into 150 mM ammonium acetate at pH 7.

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.
