Whey protein isolate (WPI) with ≥ 90% protein content was gifted by Fonterra Co-operative Group Limited (Auckland, New Zealand). Dextran (Dx) of molecular weight (MW) 500 kDa and porcine pepsin (P7000, measured enzyme activity: 371 U mg -1 using haemoglobin as the substrate) were purchased from Sigma-Aldrich Company Ltd (Dorset, UK). Medium-chain triglyceride (MCT-oil) Miglyol ® 812 with a density of 945 kg m 3 at 20 o C was used as the lipid phase (Cremer Oleo GmbH & Co, Germany) . Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) reagents including Bolt™ 4-12% Bis-Tris Plus gels, 20x Bolt™ MES SDS Running Buffer, 4 x Bolt™ LDS Sample Buffer and PageRuler™ Plus Pre-stained Protein Ladder were purchased from Thermo Fisher Scientific (Loughborough, UK). All reagents were of analytical grade and used without further purification unless otherwise reported. All solutions were prepared with Milli-Q water with a resistivity of 18.2 MΩ cm at 25 °C (Milli-Q apparatus, Millipore, Bedford, UK). Sodium azide (0.02 wt %) was added as a preservative.

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.
