d-KLA Peptide-d30 (D-(KLAKLAK)2-d30) is the deuterium labeled d-KLA Peptide (HY-P10285). d-KLA Peptide is a synthetic pro-apoptotic peptide. d-KLA Peptide can specifically target mitochondria and induce apoptosis by destroying the mitochondrial membrane. d-KLA Peptide activates biochemical pathways associated with apoptosis, including the activation of caspase family proteins and PARP (poly ADP ribose polymerase). d-KLA Peptide can be used to carry and deliver genes or small molecules to enhance anti-tumor effects[1][2].
