TPEN sc-200131 100 mg $96.00

TPEN is a cell permeable, high-affinity heavy metal (Zn2+>Fe2+>Mn2+) chelator that exhibits low affinity for Mg2+ and Ca2+. The compound is lipid-soluble and has been shown to permeate artificial and natural membranes. Research shows that TPEN induces apoptosis in human and rat thymocytes through DNA fragmentation and Caspace-3 activation. TPEN also induces mitochondrial cytochrome C translocation to the cytosol in human PBL. A recent study has proved this chelator to work in conjunction with the fluorescent probe Fura-2 (sc-202163) in biophysical studies of Ca2+.
