Area of Science:

  • Biochemistry
  • Analytical Chemistry

Context:

  • Thymopentin is a synthetic peptide with potential therapeutic applications.
  • Ensuring peptide stability during preparation is crucial for its efficacy and safety.

Purpose:

  • To evaluate the stability of thymopentin under various preparation conditions.
  • To determine optimal storage and handling parameters for thymopentin.

Summary:

  • High-performance liquid chromatography (HPLC) was employed to assess thymopentin's stability.
  • Stability was tested across different temperatures, sonification times, and pH values.
  • Thymopentin remained stable when stored frozen, at 60°C for 24 hours, and in phosphate buffer solutions (pH 2-7) at 37°C for 24 hours. Sonification up to 15 minutes was also found to be safe.
