Observations

  • No molecular formula is assigned to this material. The reference source describes it as: Recombinant peptide/protein; ~9.1 kDa.
  • Mass spectrum: no molecular weight is declared for this material, so the acquired m/z values are not assigned to charge states. The spectrum is published as acquired.

Method: purity by reversed-phase HPLC with UV detection, reported as peak area percent; identity by liquid chromatography–mass spectrometry (LC-MS) on the same sample. Full chromatographic conditions are held on file and issued on request against this search code.
