Possible Interaction: Heparin and Zinc Cation

“The metal ions Cu2+, Zn2+ , Fe2+ and Fe3+ inhibited heparin binding, with half-maximal inhibition of binding to lactoferrin occurring between 600 microM and 1 mM and for lysozyme between 500 and 800 microM. 3.”

“The uv absorption spectra and melting profiles of an initially ion‐free solution of E. coli unfractionated tRNA are significantly modified by the addition of either Na+, Mg2+, or Mn2+ or of other first‐series transition‐metal ions such as Ni2+, Co2+, and Zn2+.”
