Objectives

  • Obtain UV/Vis spectra for Au/Lysozyme samples with varying mole ratios.
  • Purify ADA from E. Coli

Procedure

  • Au/Lysozyme samples prepared last Wednesday were analyzed by UV/Vis using disposable plastic cuvettes. The instrument held a blank cuvette of water, which was automatically subtracted from the spectra of the Au/Lysozyme.
  • Samples from 134-140 showed variation in the background. In order to determine whether this was due to Lysozyme or variation in cuvettes, these trials were repeated using the same quartz cuvette. A blank of water was run using the same cuvette and subtracted from each spectra manually.
  • Puja Moody purified ADA from E. Coli grown last week
