Method for Measuring the Activity of Deubiquitinating Enzymes in Cell Lines and Tissue Samples

The overall goal of the following experiment is to visualize the activity of de ubiquitinated enzymes in cells. This is achieved by culturing cells to high co fluency and harvesting them to facilitate the production of a concentrated lysate as a second step. Gentle mechanical lysis is used to produce a lysate that maintains a metabolic picture of the cell's cytoplasm.

Next, the enzymes are incubated with hemagglutinin derived probes in order to label the de ubiquitin enzymes by reacting with the active site cysteine residue, the results show the activity profiles of many de ubiquitin enzymes based on Western blotting and subsequent chemiluminescent detection. The main advantage of this technique over existing methods like regular western blotting, is that it allows the user to visualize the activities of multiple enzymes. In one experiment, Prepare cell culture media by Ali, quoting 30 milliliters of dobe docos, modified eagles medium, or DMEM plus 10%fetal bovine serum into a 50 milliliter conical tube to culture.
