Interpreting the information supplied with your peptide
You will receive two quality control traces with your custom peptide, a mass spectrometry (MS) trace and a high performance liquid chromatography (HPLC) trace.
MS traces are used to confirm the molecules present after a peptide synthesis reaction.
Your MS trace should look similar to the one shown above for SIINFEKL peptide. The largest peak corresponds to the major ion species created from your peptide in the mass spectrometer. The value assigned to it should be close (within 1Da) to the calculated molecular weight for your peptide.
