Here, we present a protocol to construct artificial lipid droplets to study the binding affinity of lipid droplet-associated proteins. We provide procedures to construct adiposomes and prepare recombinant lipid droplet-associated proteins. Then we describe approaches to measure the number density of perilipin 2 on natural lipid droplets, construct artificial lipid droplets, and determine the binding affinity of perilipin 2 on artificial lipid droplets. This protocol can be adapted to determine the binding properties of various lipid droplet-associated proteins. For complete details on the use and execution of this protocol, please refer to Ma et al. (2021).
