Phospho-Tag™ Phosphoprotein Gel Stain



Phospho-Tag™ Phosphoprotein Gel Stain is a high sensitive fluorescent stain designed for selectively detecting phosphoproteins in polyacrylamide gels. This stain contains a phospho-tag™ group, which allows direct, in-gel detection of phosphate groups attached to tyrosine, serine, or threonine residues, without the need for antibodies or radioisotopes. The stain can be used with standard SDS-polyacrylamide gels or with 2-D gels.


  • High sensitivity. Detect as little as 1 ng phosphoprotein.
  • Simple and fast staining.
  • Compatibility with standard laboratory equipment.
  • Wide linear detection range. At least three orders of magnitude.
  • Compatible with downstream analysis: Compatible with MS and sequencing.
  • Stable: Stable at room temperature for 1 year.
