WebThe labeled peptides were then fractionated using a high pH-reversed phase peptide fractionation kit and concentrated by vacuum centrifugation. LC-MS/MS Analysis. LC-MS/MS analysis was performed on the Q Exactive Mass Spectrometer (Thermo Scientific). The obtained peptides were loaded into a reversed-phase trap column and connected to a C18 … WebIn the present work, an orthogonal two-dimensional (2D) capillary liquid chromatography (LC) method for fractionation and separation of proteins using wide range pH gradient ion exchange chromatography (IEC) in the first dimension and reversed phase (RP) in the second dimension, is demonstrated. In the first dimension a strong anion exchange (SAX) …

WebThe High pH Reversed-phase Peptide Fractionation Kit includes a high pH buffer (0.1% triethylamine) and twelve spin columns containing pH-resistant reversed-phase resin. Each reversed-phase fractionation spin column enables fractionation of 10 to 100μg of peptide sample using a microcentrifuge. WebHigh-pH reversed-phase chromatography is a robust method of peptide fractionation that separates peptides by hydrophobicity and provides excellent orthogonality to low-pH … portland maine homeless resources
