Protein binding to eppendorf/cuvette walls.

Many commercial enzymes sold as solutions include either BSA or glycerol
to prevent adsorption to the walls of tubes.  Also, ethylene glycol
(5-10%) is used in the buffer for thrombin to keep it from sticking to
tube walls.  Without the EG, you just don't get any thrombin activity.

I hope this helps
