| There is no evidence before me of the solubility either of divalent or of heptavalent manganese. |
|
| Our observations support the claim that monovalent or divalent cations are not necessary to polymerize G-actin into F-actin. |
|
| Experiments with erythrocytes were repeated with either sodium sulfate or sodium nitrate replacing the divalent ion at the same concentration. |
|
| In an alternative model, two pairs of the negatively charged residues would chelate two divalent cations. |
|
| On different days, the standard protocol was repeated with the diluent containing different divalent ion concentrations. |
|
| However, EDTA is not ideal because it also binds essential divalent cations such as calcium and zinc. |
|
| Thus, the competition between monovalent and divalent cations acts only on the DNA sites and does not act on the mica sites. |
|
| When the divalent cation dissociates from actin, the affinity of actin for nucleotide is greatly reduced. |
|
| Precipitation of NCP occurs for a threshold of divalent cation concentration, and redissolution is observed for further addition of salt. |
|
| In general, manganese ions are found in different valence states from divalent to septavalent. |
|
| These channels appear to be plasma membrane-located and non-selective, being permeable to both monovalent and divalent cations. |
|
| These findings indicate that in physiological conditions the divalent counterions are not chemisorbed on the surface of the DNA molecule but are confined in a narrow sheath. |
|
| Finally inclusion of EDTA in the reaction mixture inhibited the binding reaction suggesting that the divalent cations are essential for this binding activity. |
|
| Fully deprotonating both acidic residues would appear to totally alter the selectivity of the channel, making it more suitable for divalent ions than monovalent ones. |
|
| The receptor recognition site can change its electrovalence and exchange divalent or monovalent counter ions for either decamethonium or muscarone. |
|
| It has been reported that doxorubicin can be concentrated to such an extent within liposomes that gelation takes place in the presence of the divalent sulfate counterion. |
|
| We also observed qualitatively distinct behavior between the alkali-earth metal ions and the divalent transition metal ions in their action on the charged viruses. |
|
| The hydrophobic fourfold channels, in contrast, present large energy barriers for both monovalent and divalent ions, practically insurmountable for the latter. |
|
| The anomalously large LCTE values for europium and ytterbium again confirm the divalent nature of those two metals. |
|
| Fe is predominantly five-fold coordinated, and bond-valence calculations indicate it to be divalent. |
|
|
|
| This method uses a continuous flow vapour generator to reduce the divalent mercury to its atomic state with stannous chloride. |
|
| Use of a divalent metal salt of bacitracin for the manufacture of a medicament for treatment of protozoal infection. |
|
| Measurement of particulate and gaseous divalent mercury is also recommended. |
|
| The trivalent ions are ten times more effective than the divalent ion. |
|
| Two iron ions are trivalent, while one is divalent. |
|
| The product contains the amino acid EDTA, a chelating agent that binds divalent and trivalent metal ions, which are then excreted in the urine. |
|
| Ytterbium, like europium, is a divalent metal. |
|
| In IT2, the characterization of ionic environment effects will be completed with selected members of the Cry1 family of B. thuringiensis toxins using divalent ions. |
|
| A catalytic composition useful for decomposition and removal of malodorous components comprising a phosphate of a tetravalent metal, a hydroxide of a divalent metal, and a photocatalyst. |
|
| Divalent cation inhibition of hormone release from isolated adenohypophysial secretory granules. |
