Studying lipid-protein interactions is central to understanding lipid signaling, a key regulatory system in cells. To better identify lipid-binding proteins, we developed a nonquenched fluorescent (NQF) liposome that is able to carry both fluorescent molecules and a lipid of interest. By combining the strength of NQF liposomes with protein microarray technology, the method presented here facilitates high-throughput screening of lipid-protein interactions. This protocol describes how to prepare NQF liposomes and apply the fabricated liposomes to yeast proteome microarrays.
