Immobilized phospho-aminoacids provide a convenient and rapid purification procedure for proteins that bind to particular phosphorylated amino acids [1-3].

Jena Bioscience offers affinity chromatography material that is taylor-made for purification (or for related assays) of particular phospho-aminoacid binding proteins since we offer different types and lengths of linkers and provide different types of chromatography material ranging from bulk media to pre-packed columns that fit any machine.
