Sigma Aldrich Fine Chemicals Biosciences Molecular sieves 4 A bead1KG
Regeneration or ActivationA saturated molecular sieve can be restored to its original capacity by regeneration the principle of which involves changing the conditions surrounding the adsorbent to correspond to a very low equilibrium capacity. In general the greater the difference between the equilibrium capacities of adsorption and regeneration the more rapid and complete the regeneration.The sieve may be regenerated in one of four ways1. Thermal reactivation -The maximum regeneration temperature for Silica is 300C.2. Pressure reactivation3. Passing an appropriate fluid through the gel bed at normal temperature and pressure.4. Displacement of adsorbates by passing a high concentration of molecules in a fluid through the bed.

Cayman Chemical 15-hydroxy Prostaglandin Dehydrogenase Inhibitor Screening Kit, 384 Well
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.
