In situ 1 µM Proteinase K Kinetics RunObjectives To run the 1 nM (µM) concentration of Proteinase K and track over time for kinetics workup. Protocol Take 0.046 mL of dilution from step 4 above in 1.954 mL of Tris/NaCl buffer for a final [proteinase K]final = 10 nM. From there, dilute by a factor of 10 to decrease the final concentration to 1 nM. Ocean Optics will be run at 37°C, scanning every 5 minutes for 6 hours. Results The incorrect stock solution was used to make the protease solution. The concentration being tested is not 1 nM. It was calculated to be 1 µM of protease. This reaction will be rerun tomorrow with the proper enzyme concentration. Proper Sample Prep
Bradford Analysis of Samples from YesterdayObjectives Bradford analysis of the samples extracted yesterday will be run. Protocol A 1 in 4 Bradford assay was made (1 mL Bradford in 3 mL of Tris/NaCl buffer). |
