Objective

  1. Run Ocean Optics for Lysozyme protein with a pH of 5.

Description

  1. Make solution for cuvette. Concentrations can be found in the Data section below.
  2. Run Ocean Optics data every two minutes for 3 hours.

Data

Stock solutions

  1. Lysozyme
    1. concentration = 225 μM
  2. AuCl3
    1. concentration = 3.73 mM

Instructions for making sample for ocean optics
