Twenty micrograms of total cellular and EV lysates were separated by SDS-PAGE before transferring to PVDF membrane (Pall Australia, VIC, Australia), as described in [4 (link)]. The membrane was blocked overnight with 5% skim milk in PBS and 0.05% Tween 20 and then incubated with anti-P-gp mAb (clone F4; Sigma-Aldrich), anti-Ezrin mAb (clone 3C12; Life Science), anti-Moesin mAb (clone 38/87; Sigma-Aldrich), anti-Radixin pAb (SAB2500859; Sigma-Aldrich) or anti-CD44 pAb (HPA005785; Sigma-Aldrich) for 1 h. Anti-β-actin (clone AC-74; Sigma-Aldrich) was used as the internal control, followed by 1 h incubation with anti-Mouse HRP secondary antibody (Promega, NSW, Australia) at a 1:10,000 dilution. Protein expression was visualised using the ECL (enhanced chemiluminescence) system (Roche Applied Science, Castle Hill, NSW, Australia). The membranes were imaged using the luminescent image analyser LAS-3000 (Fujifilms, Brookvale, NSW, Australia).

Twenty micrograms of total cellular and MP proteins were separated on SDS-PAGE, as described earlier, before transferring to PVDF membrane (Pall Australia, VIC, Australia). The membrane was blocked overnight with 5% skim milk in PBS and 0.05% Tween 20, and then incubated with anti-P-gp mAb (clone F4; Sigma-Aldrich), anti-Ezrin mAb (clone 3C12; Life Science), anti-Moesin mAb (clone 38/87; Sigma-Aldrich), anti-radixin pAb (SAB2500859; Sigma-Aldrich) or CD44 mAb (clone EPR1013Y; Abcam) for 1 h. Anti-β-actin (clone AC-74; Sigma-Aldrich) was used as the internal control, followed by horseradish peroxidase conjugates secondary antibody. Protein expression was visualized using an ECL (enhanced chemoluminescence) system (Roche Applied Science, NSW, Australia). The membranes were imaged using the luminescent image analyser LAS-3000 (Fujifilms, Brookvale, NSW, Australia).

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.
