Objective

Use pepsin to cleve the peptide bonds in hemoglobin and observe its catalytic activity with and without pepstatin. The data collected will be used in a future experiment.

Protocol

The procedure for the lab can be found in Dr. Hartings lab notebook.

  • Noted differences:
    • Instead of 1.7 M perchloric acid, it was 1 M of perchloric acid.
    • For the concnetration of pepstatin added, the group decided upon 0.2 μM.
    • The stock solution of pepsin was diluted from 12μM to 2nM using .83μL in 5mL total solution (solution being hemoglobin)
    • For a reference in the UV-Vis, hemoglobin stock solution was diluted from 10μL to 1mL.

Data

  • UV-VIS spectra data, taken at 1/2 hour intervals
