Assay Method Information

Assay Name:  Inhibitory Activity Assay
Description:  Streptavidin (manufactured by Vector Laboratories) was dissolved in a 0.1M carbonate buffer solution (composition: 90 nM Na2CO3, 10 mM NaHCO3) to a concentration of 40 μg/ml, Each 50 μl of this solution was added to a well of an immunoplate (manufactured by NUNC), this is allowed to stand at 4° C. overnight to adsorb. Then, each well was washed with a phosphate buffer (composition: 13.7 mM NaCl, 0.27 mM KCl, 0.43 mM Na2HPO4, 0.14 mM KH2PO4) two times, and 300 μl of a phosphate buffer containing 1% skim milk to block it for 30 minutes. Further, each well was washed with a phosphate buffer two times, 50 μl of a substrate DNA solution (2 pmol/μl) was added to adsorb at room temperature for 30 minutes while shaking, and this was washed with a phosphate buffer two times and, then, distilled water once.
