| These channels appear to be plasma membrane-located and non-selective, being permeable to both monovalent and divalent cations. |
| It explains the method of claim 2 in which the monovalent group comprises a phosphoryl group. |
| It shall be carried out in the areas listed in Annex I with a bivalent vaccine and in the areas listed in Annex II with the monovalent vaccine. |
| The resulting dimer forms an ion channel in lipid membranes that is selective for monovalent cations only. |
| A comparison of the effect of monovalent counterions and bivalent counterions is a subject of our future work. |
| Thus, the competition between monovalent and divalent cations acts only on the DNA sites and does not act on the mica sites. |
