Notes0.001g BSA and 0.001g were added to 10mL 50mM Acetate Buffer, pH 3.6. We were unable to take an accurate enough measurement to add 0.0008g, so instead 0.001g of HAuCl4 was added. A Shimadzu UV-2550 was used. At time 0 the UV-Vis was used to take a spectra of the solution. And at 12:04pm the solution was placed in the oven at 78 degrees. At 12:34 the solution was removed from the oven and another UV-Vis was spectra as taken. The solution was placed back in the oven, now at 69 degrees, at 12:41. At 1:11 the solution was removed, and a spectra taken. It was placed back in the oven at 1:17, the oven was 78 degrees. It was removed at 1:47, measured and replaced at 1:51 with a temperature of 70 degrees. It was removed again at 2:27, measured and replaced at 2:38 with a temperature of 74 degrees. Removed at 3:06, measured, replaced at 3:12 at 70 degrees. Removed for the final time at 3:35 and measured. Oven temp 64 degrees. Wrapped in foil and set at room temperature.
