ObjectiveTo analyze the activity of proteinase k at 10 nM using fluorescence DescriptionThe guide for analyzing a protease with fluorescence can be found here at Dr. Hartings notebook
ResultsThe image below shows the intensity for the fluorescence of samples and blanks from 400 to 650 nm.
The 135 minute sample should be re-run as it is far too high of a value relative to the others. Also, more data points should be taken between 2 hours and 24 hours. Otherwise there is a general trend in increasing peptide concentration over time. |
