NTA

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性后，ELISA结果证实其具有良好的结合β3抗原活性。

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.

粉中掺入螯合，例如次氮基三（NTA）或者是二胺四（EDTA），这些螯合易于形成水溶性的金属螯合物。
