We offer a wide range of products for protein mass spectrometry. Our discovery quantitation reagents and kits enable higher multiplexing using SILAC NeuCode technology or TMT11plex isobaric labeling. Achieve relative or absolute quantitation for targeted applications by using SureQuant Targeted MS assays or Heavypeptide AQUA custom peptides. Our sample preparation products enable efficient abundant protein depletion, immunoprecipitation, protein digestion, phosphopeptide enrichment, and peptide clean-up. Our calibration solutions, standards and solvents are optimized for instrument calibration and QC. Use our interactive workflow guide or access our technical resources to find the the best product for your application.

Featured protein mass spectrometry categories
