Size-exclusion liquid chromatography for effective purification of amphiphilic trinuclear gold(I) pyrazolate complex

Ion Exclusion Chromatography: Liquid Chromatography

terials, operated in a pressure-driven mode, plotted as a function of inverse temperature. This Rgure is intended to give some appreciation of the Suxes that are attainable; however, they are not normalized to a given partial pressure gradient or thickness of membrane, and thus the Suxes are not directly comparable. Taking a value of between 10 and 100 L m 2 min 1 as the level of oxygen Sux nee...

Size Exclusion Chromatography of Polymers

In the characterization of polymers, size-exclusion chromatography (SEC) has become a standard technique for determining molar mass averages andmolar mass distributions (MMD) of polymers. The principle of SEC is easily understood: owing to limited accessability of the pore volume within the particles of the column packing, polymer molecules are separated according to their hydrodynamic volumes,...

Purification of filamentous bacteriophage for phage display using size-exclusion chromatography.

High Pressure Liquid Chromatography Purification

Two single-stranded nucleic acid-binding proteins, UP1 and UP2, that were originally reported by Herrick and Alberts (Herrick, G., and Alberts, B. (1976) J. Biol. Chem. 251,2124-2132) have been purified to apparent homogeneity from calf thymus by high performance liquid chromatography. The amino acid sequence of UP1 (Williams, K. R., Stone, K. L., LoPresti, M. B., Merrill, B. M., and Planck, S....

Sulfate-bridged dimeric trinuclear copper(II)–pyrazolate complex with three different terminal ligands

The reaction of CuSO4·5H2O, 4-chloro-pyrazole (4-Cl-pzH) and tri-ethyl-amine (Et3N) in di-methyl-formamide (DMF) produced crystals of di-aqua-hexa-kis-(μ-4-chloro-pyrazolato-κ(2) N:N')bis-(N,N-di-methyl-formamide)di-μ3-hydroxido-bis-(μ4-sulfato-κ(4) O:O':O'':O'')hexa-copper(II) N,N-di-methyl-formamide tetra-solvate dihydrate, [Cu3(OH)(SO4)(C3H2ClN2)3(C3H7NO)(H2O)]2·4C3H7NO·2H2O.
