Description & Specifications


Quantity 200pmol
Storage Requirements −30° to −10°C

  • Mixture of 30 peptides; 6 sets of 5 isotopologues of the same peptide sequence
  • Amino acids prone to artificial post-translational modification (i.e., methionine, asparagine, etc.) were excluded from the sequences
  • None of the peptides have internal lysines or arginines and will therefore not be affected by trypsin or Lys-C
  • There is a mass separation of at least 4 Daltons between the isotopologues, so that even low-resolution instruments can distinguish the masses
