摘要: The present invention provides devices and compositions for the management of infection of topical lesions, each of the devices and compositions containing protonated/acidified nucleic acids either on its surface, or integrated into the device. These modified nucleic acids are effective as bactericidal and/or bacteriostatic agents without regard to the class of bacteria, so are especially useful when diagnosis is difficult or when multiple infectious organisms are present. The antibiotic activity of nucleic acids of the invention is not dependent on either the specific sequence of the nucleic acid or the length of the nucleic acid molecule. The nucleic acids used in the invention are protonated/acidified to give a pH when dissolved in water of less than pH 7 to about 1, more preferably less than pH 4.5 to about 1, and even more preferably less than pH 2 to about 1.

摘要: Concentration of oligonucleotides in salt solutions is accomplished by loading a solution of the oligonucleotide dissolved in aqueous sodium chloride or other salt solution onto a reverse-phase poly(styrene-divinylbene) liquid chromatography (LC) column. The column bearing oligonucleotide is then washed with water to low conductivity and eluted with an organic eluent such as ethanol, thus effecting a combination desalting concentration procedure in one step, thus this procedure has utility in the desalting and concentration of oligonucleotides that have been purified and/or treated by anion exchange chromatography. In situ cationic exchange of the associated cation of the oligonucleotide can also be incorporated into the procedure of the new invention.
摘要翻译: 盐溶液中寡核苷酸的浓度通过将溶解在氯化钠水溶液或其它盐溶液中的寡核苷酸溶液加载到反相聚(苯乙烯 - 二乙烯基苯)液相色谱(LC)柱上来完成。 然后将带有柱的寡核苷酸用水洗涤至低电导率,并用有机洗脱液如乙醇洗脱,从而在一步中实现脱盐浓缩程序的组合,因此该方法可用于脱盐和浓缩已经纯化的寡核苷酸, /或通过阴离子交换色谱法处理。 寡核苷酸的相关阳离子的原位阳离子交换也可以并入新发明的方法中。
