Metabolite Extraction and CE-TOF/MS Analysis

Metabolite extraction was performed according to our previous method (Pinsorn et al., 2018 (link)). In brief, the freeze-dried sample (5 mg, five replicates) was mixed with methionine sulfone and camphor 10-sulfonic acid as internal standards (Sigma-Aldrich, St. Louis, MO, United States). CE-TOF/MS analysis was then performed as previously described (Oikawa et al., 2011 (link)). methionine sulfone and camphor 10-sulfonic acid were used for cation and anion analyses, respectively, and their peak areas were used to normalize the peak areas of metabolites, providing the relative intensity of each metabolite. In addition, the CE-TOF/MS data of the ripe-stage durian harvested in 2016 were retrieved from our previous paper (Pinsorn et al., 2018 (link)).

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.
