In this paper, we describe denaturing and non-denaturing ion-pair reversed-phase liquid chromatography (RPLC) methods for analyzing small interfering ribonucleic acid (siRNA). Drug formulations consisting of one or two siRNA duplexes were analyzed in

Introduction: Breast cancer (BC) is a complex heterogenous disease and is a leading cause of death in women. Following primary BC therapy ~40% of patients will develop metastatic BC (MBC) and 60-70% of the recurrent disease will occur at distant site

Analysis of diastereomers of phosphorothioate oligonucleotides in ion-pairing reversed-phase liquid chromatography is affected not only by the character and concentration of ion-pairing system, but also by the separation temperature. In this work, ei

Ion-pairing reversed-phase liquid chromatography was utilized for the analysis of native and phosphorothioate oligonucleotides of the identical sequence but different amount and position of phosphorothioate modifications. The effects of ion-pairing a

Nonspecific adsorption has been a consistent challenge in the analysis of oligonucleotides. Nonspecific adsorption is a result of interactions between charged acidic analytes and adsorption sites present in metallic surfaces located in the fluidic pa

Interactions of analytes with metal surfaces in high-performance liquid chromatography (HPLC) instruments and columns have been reported to cause deleterious effects ranging from peak tailing to a complete loss of the analyte signal. These effects ar
