Quality

qualityAll of our peptides are identified using MALDI mass spectrometry, on equipment calibrated using internal and external calibration standards.  We provide mass spec data with each peptide as standard, and all purified peptides come with an analytical HPLC trace if required.  We also offer:

  • Liquid Chromatography-Mass Spectrometry
  • Electrospray mass spectrometry
  • Amino Acid Analysis/ Peptide Content Analysis
  • N – C terminal sequencing
  • Nuclear Magnetic Resonance (NMR) data
  • Stability testing

Our analysis and QC suites are equipped with analytical HPLC systems for determining peptide purity, Matrix Assisted Laser Desorption Ionisation Mass Spectrometry (MALDI) for highly accurate determination of peptide identity, Electrospray Ionisation Mass Spectrometry for determination of small peptides and characterization of reagents, and Ultraviolet Spectrophotometers, as well as a range of other instrumentation.
