General description

The PHOS-Select™ iron affinity gel is a novel iron [Fe(III)] chelate matrix. This matrix provides high capacity affinity binding of molecules containing phosphate groups.

Application

Phos-Select™ products facilitate a number of applications including:
  • affinity enrichment of phosphopeptides obtained from protein tryptic digests
  • direct transfer of phosphocompounds for analysis (HPLC or mass spectrometry)
  • enrichment of phosphopeptides by immobilized metal affinity chromatography (IMAC)

Other Notes

Phos-Select™ Iron Affinity Gel is a novel iron [Fe(III)] chelate matrix based on Sigma′s NTA analog chelate ligand. The matrix provides high capacity affinity binding of molecules containing phosphate groups.

Post Translational Modification

Post-translational modifications such as glycosylation, phosphorylation, and sulfation, to name a few, serve many functions. As a result, the analysis of proteins and their post-translational modifications is particularly important for the study of diseases where multiple genes are known to be involved, such as heart disease, cancer and diabetes.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
