Studies comparing the absorption and retention of various forms of trace minerals in horses have yielded mixed results. The objective of this study was to compare Cu and Zn absorption and retention in exercising horses where the mineral was supplemented in the sulfate or organic chelate form. Nine mature horses were used in a modified switchback design experiment consisting of seven 28-d period...

The title zinc bis(thiosemicarbazone) complex, [Zn(C 22 H 17 N 4 O 2 S) ], comprises two , S -donor anions, leading to a distorted tetrahedral donor set. resultant five-membered chelate rings are nearly planar and form dihedral angle of 73.28 (3)°. configurations about the endocyclic- exocyclic-imine bonds Z E respectively, that ethylene bond is . major differences in conformations ligands seen...

We describe snap-to-it probes, a novel probe technology to enhance the hybridization specificity of natural and unnatural nucleic acid oligomers using a simple and readily introduced structural motif. Snap-to-it probes were prepared from peptide nucleic acid (PNA) oligomers by modifying each terminus with a coordinating ligand. The two coordinating ligands constrain the probe into a macrocyclic...

Recently, we developed reversible metal chelate stains that are fully compatible with immunoblotting and protein sequencing. Membrane supports are incubated in Ferrozine/ferrous complex followed by ferrocyanide/ferric complex (double-metal chelate [DMC] stain). Proteins are quantified by computerized densitometry. In this study, the metal chelate stains are used for routine protein quantitation...
