Abstract: A method for measuring elastase inhibition activity is provided to screen, identify and quantify an elastase inhibitor in a sample through a simple method of putting an agar medium under constant temperature condition without requiring a separate measuring instrument. A method for measuring elastase inhibition activity comprises the steps of: (a) preparing a solid culture medium using agar medium including 0.01-1.0 wt.% of Elastin-Congo red; (b) after adding a sample which is subject to elastase inhibition activity measurement to the solid culture medium and putting it in an incubator under constant temperature condition of 30-42 deg.C for 3-72 hours, measuring a diameter of halo shown on the culture medium.

Abstract: PURPOSE: A method for enhancing activity of a target protein expressed in inclusion body type is provided to enhance activity of the inclusion body of target protein for therapy, research, and industry. CONSTITUTION: An inclusion body of a target protein enhances the activity by treating catabolite repressor or inducer analog in a microorganism which is transformed with arabinose-inducible expression vector derived from arabinose operon having a nucleic acid encoding the target protein. An inhibitor of metabolic product is methyl α-D-glucopyranoside. The inducer analog is D-fucose. The promoter of the expression vector is araBAD. The microorganism is E.coli, MC1061.
