Figure 6. Assembling a Droplet Interface Bilayer transport system.
1. Mix aqueous phase together, comprising either A: MFS protein reconstituted into LUVs or B: cell-free reaction with added empty liposomes and template DNA. Prepare second droplet containing substrate and empty liposomes. 2. Submerge sub-microlitre droplet of the aqueous phase in hexadecane solvent bath and incubate to allow monolayer formation around each individual droplet. 3. Manipulate two droplets together so that a bilayer interface is formed between them. 4. Use microscopy to take images of the DIB and to track the transport of fluorescent substrates.
