Molecular sieves are crystalline metal aluminosilicates having a 3-dimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size. The 3A form is made by substituting potassium cations for the inherent sodium ions of the 4A structure reducing the effective pore size to ~3A… excluding diameter 3A… e.g. ethane. The 4 to 8-mesh type is normally used in gas-phase applications. Molecular sieves are considered a universal drying agent in polar and nonpolar media.
Cayman Chemical 15hydroxy ProstaglndIn Dehy
Cayman’s 15-PGDH Inhibitor Screening Assay Kit provides a robust and EAsy-to-use platform for identifying novel inhibitors of human 15-PGDH, the enzyme that catalyzes the oxidation of prostaglandins to 15-keto metabolites with reduced biological activity. Measurement of 15-PGDH activity is carried out by monitoring the reduction of NAD+ to NADH. The reduction of NAD+ to NADH is accompanied by an increase in fluorescence at 445 nm following excitation at 340 nm. The potent and reversible 15-PGDH inhibitor ML-148 Assay Reagent is included as a positive control and inhibits 15-PGDH with an IC50 value of 11 nM.
