Primary structure determination offers physical characterization of polypeptides. This technique is now crucial for process development, formulation, and quality assurance of protein products in biotechnology.

Area of Science:

  • Biochemistry
  • Biotechnology
  • Analytical Chemistry

Background:

  • Primary structure determination and related techniques like amino acid analysis, peptide mapping, and polyacrylamide gel electrophoresis have long been used for polypeptide characterization.
  • These methods have traditionally been confined to the research domain.

Purpose of the Study:

  • To highlight the expanding application of primary structure determination and associated techniques.
  • To demonstrate their value in addressing challenges in process development, formulation, and quality assurance (QA) of protein products.
  • To emphasize the significance of these techniques in detecting processing events that might otherwise be missed.

Main Methods:

  • Primary structure determination
  • Amino acid analysis
