Blueberry Juice Anthocyanin Production

Check if the same lab product or an alternative is used in the 5 most similar protocols

Concentrated blueberry juice was provided by Kweichow Moutai Ecological Agriculture Industry Development Co., Ltd. (Guizhou, China). It was made from rabbit-eye blueberries from Kaili (Guizhou, China) through pulping, enzymolysis, centrifugation, concentration, and sterilization on an industrial scale. The anthocyanin content in blueberry juice detected by Key Laboratory of Carbohydrate Chemistry and Biotechnology is shown in Table S1 (Zhou et al., 2024 (link)). The cloning host Escherichia coli JM109, expression strain P. pastoris GS115, and expression vector pPIC9K were stored in Key Laboratory of Carbohydrate Chemistry and Biotechnology. The expression strain S. cerevisiae EBY100 and expression vector pYD1 were generously provided by South China Agricultural University. The gene used in this experiment was the PAD from B. amyloliquefaciens (GenBank accession number YP_003921894.1). Anti-DDDDK Tag Mouse Monoclonal Antibody was purchased from Abbkine (California, USA), FITC AffiniPure Goat Anti-Mouse IgG from Earthox (California, USA), Yeast Competent Cell Preps Kit from Sango Biotech (Shanghai, China), lactose from Macklin Biochemical (Shanghai, China), acid hydrolyzed casein from Macklin Biochemical (Shanghai, China), and yeast nitrogen base from Sango Biotech (Shanghai, China).

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.
