Protocol is the second step in a three-step process for the preparation and enrichment of phosphopeptides using immobilized metal affinity chromatography (IMAC) for the identification of the phosphopeptides by LCMS/ MS. This procedure describes the construction of microchromatographic columns, or micro-tips. - [Read Construction of Micro-Tip for Use in IMAC Protocol]
Protocol is the first step in a three-step process for the preparation and enrichment of phosphopeptides using immobilized metal affinity chromatography (IMAC) for the identification of the phosphopeptides by LC-MS/MS. This procedure is used to prepare protein extracts from WEHI-231 cells. This preparation method provides total cellular protein samples that are free of contaminating nucleic acids. - [Read Lysis and Protein Extraction from WEHI-231 Cells with TriPure Isolation Reagent Protocol]
Protocol is specifically for the further enrichment of phosphopeptides from a phosphotyrosine pull-down. This is the final step for the preparation and enrichment of phosphopeptides using immobilized metal affinity chromatography (IMAC) for the identification of the phosphopeptides by liquid chromatography tandem mass spectrometry (LC-MS/MS). - [Read Preparation and Enrichment of Phosphopeptides from Phosphotyrosine Protocol]
Protocol is the third step in a three-step process for the preparation and enrichment of phosphopeptides using immobilized metal affinity chromatography (IMAC) for the identification of the phosphopeptides by LCMS/ MS. - [Read Preparation and Enrichment of Phosphopeptides Using IMAC and LC-MS/MS]
