摘要

This work relates to the use of organic functionalized heteropolytungstates (HPTs) as protein- specific electron microscopy labels. The objective is the development of a polycationic ligand that prevents the nonspecific precipitation reaction observed between certain polycationic biomolecules and polyanionic heteropolytungstates. Simple tetra-and pentaammonium salts between Keggin HPT lb or Dawson HFT 2b and amines 3-6 or ...
