Objectives

Starter and Expression Culturess

  • The Expression Culture and Starter Culture procedures were followed with the same modifications as on 9/18. These cultures are to be used to grow more E. Coli, this time with a plasmid coding for mutated Adenosine Deaminase (ADA)
  • Samples of Au/BSA made last week were analyzed by Atomic Absorbtion Spectroscopy.
    • Before they were analyzed, solutions were centrifuged at 3000 rpm at 10°C for 5 min and fluid was separated from fibers. This is because the fibers would clog the instrument's tubing.
    • Between samples, water was run in order to clear residue.

Discussion

  • Our AA spectra is very similar to the one obtained 9/4 for 60-170 Au/BSA. Both show a drop to near-zero at 128, after an increase. This time the value at 100 is near-zero, which defies the trend and the previous results and may possibly be due to experimental error.
