1,2-Dioleoyl-sn-glycero-3-phosphocholine (DOPC), 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), cholesterol and 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-(lissamine rhodamine B sulfonyl) (ammonium salt) (Rh-DPPE) were obtained from Avanti Polar Lipids. All lipid bilayers used in fluorescence imaging were doped with 0.1 mol% Rh-DPPE. Giant unilamellar vesicles were formed via electro-formation in 300 mM sucrose solution, using standard protocols. [25] [26] [27] Around 0.5-2 µL of GUV solution was pipetted onto the PDMS substrate, previously wetted with 500 µL trizma buffer (10 mM trizma base, 150 mM NaCl, 2 mM CaCl 2 ). Within two minutes, the vesicles fused to the PDMS substrates (both partially and fully oxidized) and formed membrane patches. The remaining unfused vesicles were gently washed away with 500 µL trizma buffer.

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.
