13 NEW Standardization Kits for MS based Neo-epitope Identification

Do you have these Mass Spec problems?

Even though Mass Spec has come a long way, epitope peptides eluted form HLA ligand complexes are scarce, non-trypic and short. Therefore, they produce fewer fragment ions compared to longer tryptic peptides.

As a result, it is difficult to assign fragmentation patterns to such peptide sequences. In fact, studies show that, using standard analytical methods, more than 10% of assigned spectra do not agree with the correct synthetic reference.

Furthermore, protocols for peptide elution from HLA ligand complexes are complicated and often defy lab to lab standardization.

The answer to these problems are reference peptides that can help users to control and monitor immunopeptidomics workflows.
