Analysis and synthesis of more protein-AuNP materials. Each group will have a different task. One (set) of groups will be doing AA on their samples from last weed (HRP-AuNPs and pepsin-AuNPs) and this week (Myoglobin-AuNPs and HRP-AuNPs). Another (set) will take UV-Vis absorbance of their samples (this week and last week). The final (set) will synthesize new protein-AuNPs.
- Before any measurement, take note of physical appearance of your samples (taking pics with cell phones helps here)
- Atomic Absorption
- centrifuge (4mL of your) samples (use the large centrifuge upstairs) 30min at 4000rpm.
- make standard solutions in the same manner as the last time we performed AA. But, this time make concentrations that go up to 50ug/mL
- Take measurements of your standards and samples
- Make a graph showing concentration of Au vs Au:protein ratio
- UV Vis
- centrifuge 1mL of your sample (use the small centrifuge in 207) 30min at max rpm
- Take measurements of your samples
- Lysozyme AuNP and Myoglobin AuNP
- Determine the total amounts of materials you will need for the following samples using the same procedures as the last two times we made protein-AuNPs (final Au concentration of 0.25mM and a final volume of 5mL)
- Make your stock solutions
- Make your samples in small test tubes and cap with aluminum foil
- Heat your samples at 80C for 4 hours
