Therapeutic Enzymes Characterization Services

Enzymes are biological macromolecules with biocatalytic activity in living organisms, including proteins and nucleic acids. Most enzymes are composed of proteins or complexes of proteins and coenzymes by nature. Due to the high specificity and catalytic efficiency, enzymes are highly targeted and effective in disease treatments of all kinds. Currently, more than 2,000 enzymes have been discovered in the biological world, and among these, there are about 50-60 industrial enzymes; over 120 therapeutic and diagnostic enzymes; over 300 reagent enzymes; and over 100 enzymes were used as genetic engineering tools.

Classification and application of medicinal enzymes:

  • Digestive enzymes
  • Anti-inflammatory enzymes
  • Enzymes related to the treatment of cardiovascular and cerebrovascular diseases
  • Anti-tumor enzymes
  • Enzymes related to biological redox electron transfer
  • Other medicinal enzymes

Why Characterize Therapeutic Enzymes?

Regulatory agencies strictly govern the testing and production of therapeutic enzymes worldwide, and batch-to-batch consistency is crucially important. Batch manufacturing begins from the fermentation or cell culturing stage. Subsequently, therapeutic enzymes are expressed in a cell culture bioreactor to robust the reproducible protein purification or downstream processing (DSP) of the target product. Thus, it is critical to ensure the safe delivery of these medicines throughout the whole process. QC is highly crucial in therapeutic enzyme production to ensure the drug's identity, strength, potency, purity, and safety. As a result, QC that are capable of operating across the entire biopharmaceutical process workflow, evaluating novel enzymes as well as upgrading and improving existing ones are current needs.
