## Abstract We have developed a method for protein identification with peptide mass fingerprinting and sequence tagging using nano liquid chromatography (LC)/Fourier transform ion cyclotron resonance mass spectrometry (FTICRβMS). To achieve greater sensitivity, a nanoelectrospray (nanoβES) needle p
In this work we demonstrate the use of peptide as a stable internal mass standard to obtain accurate mass measurements of infrared multiphoton dissociation (IRMPD) generated phosphorothioate oligonucleotide fragment ions. Because oligonucleotides are more readily dissociated in the gas phase by IRMP
