General description

1,10-Phenanthroline monohydrate is the hydrated form of o-phenanthroline.

Application

1,10-Phenanthroline monohydrate (phen) may be used in the photochemical quantification of Fe3+ and total iron in mineral samples. It may be used as starting reagent for the preparation of 5-nitro-1,10-phenanthroline.
When complexed with copper, it possesses nuclease activity that has been used to study DNA-protein interactions.

Biochem/physiol Actions

Metalloprotease inhibitor; chelates iron, zinc and other divalent metals. Effective concentration 1-10 mM.

Polycomb repressive complex 2 (PRC2) places H3K27me3 at developmental genes and is causally implicated in keeping bivalent genes silent. It is unclear if that silence requires minimum H3K27me3 levels and how the mark transmits faithfully across mammalian somatic cell generations.

Quality control of peroxisomes is essential for cellular homeostasis. However, the mechanism underlying pexophagy is largely unknown. In this study, we identified HSPA9 as a novel pexophagy regulator. Downregulation of HSPA9 increased macroautophagy/autophagy but decreased the number of peroxisomes in
