Sodium selenite ∼98%, powder cell culture reagent

Catalog Number: (IC10292825)
Supplier: MP Biomedicals
Description: Sodium selenite is commonly used as a source of selenium in biological research, where selenium is an essential trace element that is normally provided by serum. Selenium is present in selenoproteins such as glutathione peroxidase and thioredoxin reductase, which contain the selenium analog of cysteine, selenocysteine. In particular, glutathione peroxidase has a role in detoxification in vivo as a scavenger of peroxides. Sodium selenite is included in various medium supplements for use in cell culture. Sodium selenite has been utilized in studies of cell proliferation and cancer research. It has been used to alter gene expression in HepG2 cells as analyzed by cDNA microarrays. Sodium selenite can inhibit zinc finger protein/DNA interactions. Sodium selenite has been shown to alter mitochondrial membrane potentials and thus potentially contribute to apoptosis.

Di-tert-butylcyclopentadiene ≥95% (by GC)

Supplier: Adipogen
Description: Building block for synthesis. Frequently used as precursors to di-tert-butylcyclopentadienyl (Cpt) ligand in many sandwich and half sandwich complexes. Di-tert-butylcyclopentadiene reacts with excess potassium tert-butoxide in the presence of elemental selenium to yield cyclopentadienes bridged by two or three selenium atoms through one or two diselenoketal functionalities. It reacts with excess potassium tert-butoxide in the presence of elemental sulfur to yield cyclopentadienes bridged by sulfur atoms via one or two dithioketal functionalities.
