Perform efficient enrichment of phosphorylated proteins derived from mammalian cells and tissues with Thermo Scientific™ Pierce Phosphoprotein Enrichment Kit.

The kit is an effective system for isolating the phosphoprotein fraction of mammalian cell and tissue lysates. The included lysis-binding buffer and proprietary affinity resin produce superior yields with negligible non-specific binding. The kit uses a convenient spin column format, and the resulting phosphorylated protein sample is compatible with downstream applications, including Western blotting, mass spectrometry (MS), 2D-PAGE, and protein arrays. The affinity resin is also available as pre-packed chromatography cartridges for use with automated liquid chromatography (LC) systems.


  • Specific – low nonspecific protein contamination from complex biological samples, such as cell culture lysate and mouse tissue extract

  • Fast – easy spin format enables enrichment of phosphorylated proteins in less than 2 hours

  • Superior yield – achieves higher yields than other commercially available phosphoprotein isolation kits

  • Convenient format – complete kit offering pre-dispensed spin columns, buffers, reagents and ultrafiltration columns for enrichment

  • Compatible – downstream applications include mass spectrometry, Western blotting and 2D-PAGE
