URANYL ION-SPECIFIC DNA APTAMER AND A METHOD FOR ISOLATING URANYL ION FROM A SAMPLE

摘要

PURPOSE: A uranyl ion-specific DNA aptamer is provided to effectively isolate uranyl ion from a sample and marine environment.;CONSTITUTION: A uranyl ion-specific DNA aptamer has a base of sequence number 1. The DNA aptamer is conjugated to a solid support. The solid support is an amino polystyrene resin. The solid support is sulfosuccinimidyl 4-(N-maleimido methyl)cyclohexane-1-carboxylate-aminopoly styrene resin. A method for uranyl ions from a sample comprises: a step of contacting the aptamer and a sample; and a step of isolating a uranyl ion-DNA aptamer complex.;COPYRIGHT KIPO 2012
