      Overview

      Description
      OverviewThe ProteoExtract® Phosphopeptide TiO2 Enrichment Kit is a useful tool for enrichment of phosphorylated peptides from complex samples by a highly selective Titanium oxide solid phase. It enhances the ability to routinely identify and characterize large numbers of phosphorylated species within complex protein mixtures taking advantage of a novel titanium dioxide material. Captured and eluted phosphopeptide fractions are ready for MALDI- and ESI- mass spectrometry analysis.

      Application Data
      Titanium dioxide allows for selective and sensitive phosphopeptide enrichment with low background from complex mixtures. A complex peptide mixture derived from a tryptic digest of porcine liver extract was spiked with α-casein and two synthetic phosphopeptides (see below for concentrations). The samples were subsequently processed using the ProteoExtract® Phosphopeptide Enrichment TiO2 Kit as outlined in the Detailed Protocol. Mass spectrometry analysis was performed using ESI-LC/MS equipment operated in positive mode. (A) Unprocessed sample (B) Phosphopeptides recovered using the ProteoExtract® Phosphopeptide Enrichment TiO2 Kit. Spiked Phosphopeptides: 1. 50 nM Angiotensin ~6 pmol/125 µl; ~7 ng/125 µl 2. 67 nM Calcineurin Substrate ~8 pmol/125 µl; ~18 ng/125 µl 3. 140 nM α-Casein ~18 pmol/125 µl; ~400 ng/125 µl
