A fast and sensitive Direct Extraction (DE) method developed in our group can efficiently extract proteins in 30 min from a 5 cm-long hair strand. Previously we coupled DE to downstream analysis using gel electrophoresis followed by in-gel digestion, which

Glycopeptide Abundance Distribution Spectra (GADS) were recently introduced as a means of representing, storing and comparing glycan profiles of intact glycopeptides. Here, using that representation, an extensive analysis is made of multiple commercial

Representing and Comparing Site-Specific Glycan Abundance Distributions of Glycoproteins

Concepcion Remoroza, Meghan Burke Harris, Yi Liu, Yuri Mirokhin, Dmitrii V. Tchekhovskoi, Xiaoyu (Sara) Yang, Stephen E. Stein
A method for representing and comparing distributions of N-linked glycans located at specific sites in proteins is presented. The representation takes the form of a simple mass spectrum for a given peptide sequence, with each peak corresponding to a
