State of the art biomolecular core facilities: a comprehensive survey
(FEDERATION AMER SOC EXP BIOL, 1991)
A survey of 124 protein and/or nucleic acid chemistry facilities has provided a basis for estimating the resources needed to establish a facility, the financial support needed to keep it operating, and the technical ...
Effect of acetate, citrate, and lactate incorporation on distribution of cadmium and copper chemical forms in soil
(MARCEL DEKKER INC, 2001)
Some organic acids of low molecular weight, generated through breakdown of giant wastes or root exudation, increase the solubilization of heavy metals, such as cadmium (Cd) and copper (Cu) through complexation reactions ...
Hydration, charge, size, and shape characteristics of peptides from their CZE analyses
(Wiley, 2008-12)
A capillary zone electrophoresis model is presented for peptide characterization, on the base of well established physicochemical equations.The effective mobility is used as basic data in the model to estimate relevant ...
Interplay Between Electrophoretic Mobility and Intrinsic Viscosity of Polypeptide Chains
(Wiley Vch Verlag, 2012-04)
The present work is motivated specifically by the need to find a simple interplay between experimental values of electrophoreticmobility and intrinsic viscosity (IV) of polypeptides. The connection between these two ...
