WebSince propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. PI binds to DNA by intercalating between the bases with little or no sequence preference. In aqueous solution, the dye has excitation/emission maxima of … WebModular and versatile METTLER TOLEDO ion-selective half-cells consist of two elements: a universal shaft and an ion-specific membrane module. This module may be exchanged allowing you to measure the ion of your choice. Just order the membrane kit specific for that ion, mount the new module onto the shaft of your ISE half-cell, and you have a new ISE!
WebRadioiodination involves the substitution of radioactive iodine atoms for reactive hydrogen sites in target molecules. The process usually involves the action of a strong oxidizing agent to transform iodide ions into a highly reactive electrophilic iodine compound (typically I2 or a mixed halogen species such as ICl).
