SDS-PAGE Prep SDS-PAGE was prepared according to the following: 10 μL 0.6 g/L lysozyme with 10μL SDS-PAGE sample buffer in 1.5 mL centrifuge vial 10 μL 0.12 g/L lysozyme with 10μL SDS-PAGE sample buffer in 1.5 mL centrifuge vial 10 μL 30:1 Au/lysozyme colloid with 10μL SDS-PAGE sample buffer in 1.5 mL centrifuge vial 10 μL 0.12 g/L unknown protein with 10 μL SDS-PAGE sample buffer in 1.5 mL centrifuge vial Placed in heating block (set at 90 °C) for 5 minutes, and placed in the fridge overnight. A pH 6.24 66 mM Potassium Phosphate buffer was prepared using monobasic and dibasic solids. Dialysis Analysis Bradford, UV-VIS, and Fluorescence analysis were run on the dialysis samples from the KI dialysis. 1 in 4 Bradford solution was prepared and the samples were prepped the same method as previously. A blank was also run. For UV-VIS and fluorescence, a 1 in 100 dilution of each was prepared and run. UV-VIS was run from 200-400 nm.
