the protein was obtained after thrombin cleavage of a gst-fusion
protein. although the thrombin was removed by a mono-q step, i added the
pmsf just to inhibit any residual thrombin left in the preparation and
avoid non-specific degradation of my protein over time.

bipin at iastate.edu             up at the beautiful stars, and i said to myself, 
n2.bkd at isumvs.iastate.edu     'where the F*CK is my ROOF !!'
