  • Documentation

Such an approach gives researchers necessary data about the identity and composition of the laboratory peptides.

Solid Phase Peptide Synthesis (SPPS)

Peptide synthesis generally involves Solid Phase Peptide Synthesis (SPPS), a proven technique that is widely used in peptide chemistry and biotechnology.

SPPS allows scientists and producers to combine amino acids in a controlled manner and thereby build up a definite peptide structure.

Production steps include:

  • Choice and preparation of peptide sequence
  • Controlled amino acid coupling
  • Rinsing away synthesis support materials
  • Peptide purification
  • Analytical work
  • Freezing and preparing
  • Production documentation and release of batch

This procedure allows producing defined peptide materials for research.

Peptide Purification Process

After the synthesis procedure, there comes the purification step allowing isolation of the desired peptide from all unnecessary substances formed during synthesis.

Purification procedures allow eliminating:

  • Incomplete peptide sequences
  • Synthesis materials
  • Peptides related to the synthesized one
  • Manufacturing contaminants

Controlled purification process allows achieving higher analytical accuracy.

Lyophilisation Process

Following purification and analysis, SS-31 is provided in lyophilised powder form.

Lyophilisation is a freeze-drying process that is often employed for research peptides.

Lyophilisation decreases the amount of moisture in research peptide while stabilising the product.

Advantages of using lyophilised research peptides include:

  • Lower moisture exposure
  • Better storage conditions
  • Ease of laboratory manipulation
