Which types of SpikeTides are available?
SpikeTides: proteotypic peptides with c-terminal Lys or Arg residue. SpikeTides T: proteotypic peptides with additional c-terminal tag. SpikeTides T need to undergo tryptic digestion to release the native proteotypic peptide. SpikeTides TL: SpikeTides T labeled with stable isotopes carrying an additional c-terminal tryptic tag. SpikeTides TL need to undergo tryptic digestion to release the heavy labeled native proteotypic peptide. SpikeTides TQ: SpikeTides T provided with information on absolute quantity for each peptide. SpikeTides TQ need to undergo tryptic digestion to release respective proteotypic peptide. SpikeTides TQL: SpikeTides T fully quantified and labeled with stable isotopes carrying an additional c-terminal tryptic tag. SpikeTides TQL need to undergo tryptic digestion to release respective proteotypic peptide.
