*Note: Protease inhibitors and BSA should be added to the buffer immediately prior to use.
BSA stock solution should be prepared at 100 mg/mL.
Note: All buffers, proteins, and tubes should be kept on ice until indicated. Assay volumes are 75 µL and are combined in 0.5 mL Eppendorf tubes. The table below Step 5 summarizes the reactions that should be set up in Steps 1-6.
