Numerous techniques are available for the isolation of cellular proteins based on their post-translational modification (PTM) or active binding site. Protein enrichment is essential for isolating low-abundant proteins or isolating protein classes. Enrichment of specific proteins or protein complexes can most easily be accomplished using target-specific immobilized antibody or PTM specific affinity binding. The novel Thermo Scientific™ ActivX™ probes and enrichment kits enable the specific targeting of several enzyme classes, including kinases, GTPases, and serine hydrolases.
- Comprehensive—reagents and kits for multiple protein enrichment strategies
- Optimized—all reagents and kits are designed to maximize protein yield and reduce nonspecific binding
- Convenient—easy-to-use spin formats enable more rapid enrichment of proteins
- Flexible—kits can be used with either cultured mammalian cells or tissues

For downstream mass spectrometry analysis, peptide enrichment and/or fractionation is often necessary to detect peptides from low-abundance proteins and/or for reducing sample complexity for proteomic analysis.
