Studying peptide interactions with model membranes have aided in understanding protein-lipid interactions more clearly. In this report, fluorescent small unilamellar vesicles (SUVs) of a known composition were made. Two peptides, RND1 and MARCKS, were also fluorescently labeled and added to a solution of SUVs. The interactions between these were observed via fluorescence quenching, read out with a spectrofluorimeter. In addition, two environments of buffer were tested: 1X PBS and 0.1X PBS. After obtaining data, it was concluded that MARCKS quenched the SUVs more than RND1. This could be due to the presence of more lysine amino acids in MARCKS, which have been known to play a role in membrane protein activity (Li et al., 2013). No significant changes were observed when the buffer conditions were manipulated.
