Objective

Learn how to maintain an OpenWetWare Notebook.

Procedure and Data

Stock solutions

As noted on Friday, OPD will oxidize in water over time. OPD and H2O2 solutions will be made fresh for each run!

sample 1

  1. Stock solutions:
    1. Myoglobin
      1. 1.4mg (Mb:KCl lyophilized from Citrate, 5mg:500mg) in 1.0mL water
    2. OPD
      1. 2.4mg OPD in 2.4mL water
    3. H2O2
      1. 0.114mL 30% H2O2 in 0.887mL water
  2. Experimental Run
    1. Sample chamber set to 5C and to stir
    2. N2 run through the cuvette holder to reduce condensation on cuvette
    3. 2.025mL OPD stock solution
    4. 0.75mL H2O2 stock solution
      1. Start Data Collection
      2. 1ms Integration
      3. 10 scan average
      4. Wait 1 minute after each scan
      5. Stop after 2 hours
    5. Files saved as: Mb_OPD_H2O2_Citrate_H20_5_SCANNUMBER.txt
    6. 0.225mL Mb stock solution added just before the third scan
    7. This is denoted in the data file for the third scan

sample 2

  1. Stock solutions:
    1. Myoglobin
      1. used same solution as above (1.4mg (Mb:KCl lyophilized from Citrate, 5mg:500mg) in 1.0mL water)
