Objective

Make calibration curves using the Bradford Assay.

Procedure

  1. Make a stock solution that is roughly 10mg protein in 2mL of buffer.
  2. Calculate your actual concentration
  3. Make 6 standard solutions (1mL each) between 1μg/mL and 10μg/mL
    1. Determine the appropriate volume of your stock to use (for the proper final concentration in 1mL) and add that volume to an eppendorf tube
    2. Add 200μL of the Bio-Rad Protein Assay reagent
    3. Add the correct amount of buffer such that the final volume is 1mL
  4. Take a UV-Vis (no less than 1 hour after they were produced).
  5. Make 2 blanks as well (800uL buffer and 200uL Assay reagent) and take it's UV spectrum. (400nm-800nm)
  6. After you have finished one set, repeat the process (make new samples and new measurements)

Make Atomic Absorption standards for tomorrow!

Using the gold AA/ICPMS standard solution make 5 new solutions (Note: Use water - NOT BUFFER - to make these solutions)

  1. 25 ug/mL
  2. 20 ug/mL
  3. 15 ug/mL
  4. 10 ug/mL
  5. 5 ug/mL

Data (Trial 1)

  1. Series 1: 5
  2. Series 2: 6
  3. Series 3: 7
  4. Series 4: 8
  5. Series 5: 9
  6. Series 6: 10

Data (Trial 2)

  1. Series 1: 5
  2. Series 2: 6
  3. Series 3: 7
  4. Series 4: 8
  5. Series 5: 9
  6. Series 6: 10

Notes

All data was collected using the shortened path length of .412 cm.
