Catalog #: 27713
Size: 0.5 ml
MW: 198.2 Da
CAS Registry #: 5144-89-8
Formula: C12H8N2 · H2O
1,10-phenanthroline (o-phenanthroline) is a chelator with high affinity for divalent metal ions. When complexed with copper, it possesses nuclease activity that has been used to study DNA-protein interactions. While not specific for DUBs, it has been shown to be a potent inhibitor of JAMM-type isopeptidases through chelation of the active site Zn2+ ion. As such, o-phenanthroline is widely used when preparing cell lysates for enrichment of proteins bearing K63-linked polyubiquitin chains which are especially sensitive to DUBs in the JAMM family.
Supplied As:
0.5M solution in anhydrous DMSO (100X)
Biological Activity:
Metalloprotease inhibitor; chelates iron, zinc and other divalent metals. Effective concentration 1-10 mM.
DMSO solution
Useful for inhibition of JAMM-family isopeptidases. Especially valuable for protecting K63-linked polyubiquitin chains in cell lysates.
