S-PE is a peptide(sequence: PCRFFESHVA) with active stem cell recruitment capacity. S-PE was screened and identified on Discovery Studio software through peptide display techniques. S-PE showed a outstanding cell homing effect with bone marrow mesenchymal stem cells (BMSCs), as well as promoted osteogenic differentiation to some extent, since S-PE is a promising target peptides simulating the functional domain of stromal cell-derived factor-1 (SDF-1).

Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides

Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.

Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.

Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.

In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
