Aggregation of nucleosomes by divalent cations [PDF]
Biophysical Journal, 2001 Conditions of precipitation of nucleosome core particles (NCP) by divalent cations (Ca2+ and Mg2+) have been explored over a large range of nucleosome and cation concentrations. Precipitation of NCP occurs for a threshold of divalent cation concentration,

Molecular determinants of ASIC1 modulation by divalent cations
Scientific ReportsAcid-sensing ion channels (ASICs) are proton-gated cation channels widely expressed in the nervous system. ASIC gating is modulated by divalent cations as well as small molecules; however, the molecular determinants of gating modulation by divalent ...

The modulation of TRPM7 currents by nafamostat mesilate depends directly upon extracellular concentrations of divalent cations [PDF]
Molecular Brain, 2010 Concentrations of extracellular divalent cations (Ca2+ and Mg2+) fall substantially during intensive synaptic transmission as well as during some pathophysiological conditions such as epilepsy and brain ischemia.

Divalent cations as modulators of neuronal excitability: Emphasis on copper and zinc [PDF]
Biological Research, 2006 Based on indirect evidence, a role for synaptically released copper and zinc as modulators of neuronal activity has been proposed. To test this proposal directly, we studied the effect of copper, zinc, and other divalent cations on voltage-dependent ...

Activation of Deoxyribonucleases by Divalent Cations [PDF]
The Journal of General Physiology, 1962 The activation of DNase I by Mg, Mn, Co, Ni, Fe, Cd, Zn, Ba, Sr, Ca, and Cu ions has been studied by several methods, at different pH and salt concentrations. Mg, Mn, and Co are the best activators for initial stages of degradation. A synergistic effect is shown only by the pair Mg-Ca. Optimal pH of action is always situated at 6.5.

Adsorption of Divalent Cations on DNA [PDF]
Biophysical Journal, 2004 The distribution of divalent ions in semidilute solutions of high-molecular-mass DNA containing both sodium chloride and strontium chloride in near-physiological conditions is studied by small-angle x-ray scattering and by small-angle neutron scattering.

Precise Control of Charge-Structure Coupling in Polyamide Membranes for Mono- and Divalent Ion Separation. [PDF]
Adv Sci (Weinh)A zwitterionic copolymer, Poly(2‐methacryloyloxyethyl phosphorylcholine‐co‐2‐aminoethyl methacrylate hydrochloride) (P(MPC‐co‐AEMA)) copolymers, with tunable MPC/AEMA ratios, is grafted onto the polyamide (PA) selective layer via secondary interfacial polymerization. Balancing reactive anchoring segments (AEMA) and zwitterionic segments (MPC) regulated

Transport of Divalent Cations [PDF]
Plant Physiology, 1979 The cation exchange capacity of the intact xylem vessels in cut shoots of papyrus (Cyperus papyrus spec.) has been determined. The cation exchange capacity is independent of the cation concentration in the transpiration stream, and is equal for Ca and Co.
