Furthermore, each batch undergoes testing for endotoxins using the Limulus Amebocyte Lysate (LAL) assay to ensure it is free from bacterial contaminants that could interfere with experimental results, particularly in cell-based or in vivo studies

Research shows that in senescent cells, p53 levels are maintained low through ubiquitination while its pro-apoptotic activity is repressed through nuclear segregation by FOXO4. The peptide's competitive inhibition restores p53 activity by promoting nuclear exclusion, allowing p53 to execute its pro-apoptotic program and eliminate senescent cells through targeted pathway activation
