We have observed that EI possesses extremely hydrophobic surface regions. In light of this property, a high yield, rapid procedure has been developed for the complete purification of EI using solely hydrophobic interaction chromatography on commercially available resins. The entire procedure can be completed in 4-5 days with a 55-65% recovery of EI activity and an 870-fold purification.
