Untargeted Quantitative Peptide Proteomics

Untargeted Quantitative Peptide Proteomics

Quantitation always requires a consultation to help design the experiment. Depending on the problem, we can use a variety of methods to perform the analysis.

  • Isotopic Label: SILAC (Stable Isotope Labelling of Amino Acids in Cell Culture)
    • Best for cell lines, few states to compare
  • Isobaric Label: iTraq/TMT
    • Best for many states. Fewer runs, expensive reagents.
  • Label-Free Peptide Quantitation
    • More runs required, no reagent needed.
