Abstract:
A cyclodextrin is prepd. by putting raw starch, attrition milling material (I) and cyclodextrin glucosyl transferase (II) into the attrition milling bioreactor, under stirring. The (I) is selected from stainless steel bead, glass bead, ceramic bead etc.. The (II) is derived from Bacillus sp.. The yield of cyclodextrin is high.

Abstract:
PURPOSE: An assay system for screening a therapeutic agent is provided to maintain structural stability and to analyze the efficacy of a protein therapeutic agent. CONSTITUTION: A method for analyzing the efficacy of a protein therapeutic agent for treating sepsis comprises: a step of transducing a vector with an expression cassette containing a NF-kappaB which binds a motif-conjugated promoter and a gene encoding a reporter protein, and a vector with an expression cassette containing NF-kappaB which binds a motif-free promoter and a gene encoding the reporter protein into a cell line on which an LPS signal transduction receptor is expressed; a step of mixing purified MD-2(myeloid differentiation protein-2), LPS and protein therapeutic agent for treating sepsis; a step of contacting the mixture with the cell line; and a step of determining whether a contacted experimental group has a higher efficacy than a control group when expression level of the reporter protein is less than the control group.
