Amino Acid Analysis is a vital tool at all stages of drug discovery and throughout the manufacturing process, where it is used to ensure consistency between drug batches. It is also a key part of the ICH Q6B guidelines in support of new marketing applications. As such, it is important that when you outsource analysis you know you are placing work into a safe and experienced pair of hands.

Amino Acid Analysis can be used for:

  • Protein concentration calculations and characterization
  • Determination of extinction coefficient
  • Total amino acids, including cysteine, tryptophan, and hydroxyproline
  • Free amino acids, including asparagine and glutamine

Our experts:

  • Carry out an optical density measurement and analyze peptide or protein content and molar ratio using reverse-phase high performance liquid chromatography (RP-HPLC)
  • Couple this process with UV spectrophotometry to determine the extinction coefficient
