Aplicación

The PhosphoProfile I Phosphopeptide Enrichment Kit is designed to increase the concentration of phosphopeptides from tryptic digests by immobilized metal affinity chromatography (IMAC). The enriched solution helps to overcome the limitations of mass spectrometry of phosphopeptides. The provided reagents are compatible with downstream LC-MS and MALDI-TOF MS analysis.

Características y beneficios

  • Low non-specific binding - high data confidence
  • No bias in phosphorylation states - accurate representation of phosphorylation types present for sample comparisons
  • Fast sample processing - reduces time to data generation from sample collection
  • Complete optimized set of reagents and enzymes - Reduce cost and effort with total sample management in one package

Otras notas

The kit is a convenient collection of all materials necessary to perform phosphopeptide enrichments from crude samples following tryptic digestion. The supplied phosphopeptide capture matrix is a novel Ga (III) chelate silica based on Sigma-Aldrich′s proprietary nitriloacetic acid (NTA) analog. The matrix is packed into spin columns for easy, microscale affinity capture of phosphopeptides.

The enrichment of phosphopeptides using immobilized metal ion affinity chromatography (IMAC) and subsequent mass spectrometric analysis is a powerful protocol for detecting phosphopeptides and analyzing their phosphorylation state. However, nonspecific binding peptides, such as acidic, nonphosphorylated peptides, often coelute and

The identification of protein phosphorylation sites from cell-derived proteins is crucial to the understanding of signal transduction pathways. While determining the modified sites on individual proteins can present a significant challenge, recent progress in the rapid, large-scale identification of phosphopeptides
