The expression product of ScFv was purified through Ni-NTA agarose metal affinity resin column and renatured.

经金属螯合亲和层析柱(Ni-NTA agarose)纯化和凝胶柱上位复后，ELISA果证实有良好的合β3抗原。

3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.

洗衣粉中掺入螯合剂，例如次氮基三乙酸酯（NTA）或者是乙二胺四乙酸酯（EDTA），这些螯合剂易于形成水溶的金属螯合物。
