Phenolic acid standards were purchased from Sigma (St. Louis, MO). All tocopherol homologues (purity > 95% by HPLC) were obtained from Calbiochem-Merck Biosciences (Darmstadt, Germany). n-Hexane (HPLC-grade) and 1.4-dioxane (HPLC-grade) were purchased from Merck (Darmstadt, Germany). A fluorescent probe NBD-PE (N-(7-nitrobenz-2-oxa--1,3-diazol-4-yl)-1,2-dihexadecanoyl-sn-glycero-3--phosphoethanolamine, triethylammonium salt) was acquired from Thermo Fisher Scientific (USA). All other solvents and chemicals used in this study were of analytical grade.

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.
