Tocopherols
CAS :<p>Tocopherols are fat-soluble vitamins that belong to the family of tocopherols and tocotrienols. Tocopherols have a number of biochemical properties and antioxidant properties. These properties make them important for maintaining energy metabolism in cells, preventing oxidation of other molecules, and protecting the body from damage by reactive oxygen species. Tocopherols are found in a variety of biological sources such as plants, vegetable oils, nuts, grains, fruits and vegetables. The most common form is alpha-tocopherol (a-T). Other forms include gamma-tocopherol (g-T), delta-tocopherol (d-T), beta-tocopherol (b-T), and alpha-tocotrienol (a-TT). Biochemical assays for tocopherols and tocotrienols use p-hydroxybenzoic acid as an analytical reagent.

CAS :Meta-Cresol Purple (MCP) is a fluorescent dye that is used to detect DNA polymerase chain reaction products. It is a cationic dye with an absorption maximum of 590 nm in the visible spectrum. MCP has been shown to bind to nucleic acids and therefore can be used as a probe for detecting DNA polymerase chain reaction products. The detection time for MCP can be up to 10 minutes. The biological studies show that MCP binds to the 3' hydroxyl group of the ribose sugar backbone of nucleic acids, which prevents the interaction of MCP with other biomolecules such as proteins. MCP has also been used in urine samples as an antimicrobial agent against bacterial strains like Escherichia coli and Pseudomonas aeruginosa and yeast strains like Candida albicans and Saccharomyces cerevisiae. MCP is soluble in sodium carbonate at neutral pH, but insoluble in water orFormule :C21H18O5SDegré de pureté :Min. 95%Masse moléculaire :382.43 g/mol2-Bromo-2',4'-dichloroacetophenone
CAS :2-Bromo-2',4'-dichloroacetophenone (2BDCA) is a drug that belongs to the class of active substances. 2BDCA has potent inhibitory activity against erythrocytes and is used in the treatment of leukaemia. 2BDCA is also an optical probe, which can be used to detect phosphate groups and dihedral angles in biological systems. It can be used as a fluorescent probe for biological systems, such as cells or proteins, and has been shown to be effective on red blood cells. 2BDCA binds to these molecules by hydrogen bonding and exhibits optical properties through fluorescence resonance energy transfer.Formule :C8H5BrCl2ODegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :267.93 g/molNorfluoxetine HCl
CAS :Fluoxetine is a selective serotonin reuptake inhibitor that belongs to the group of drugs known as antidepressants. Fluoxetine inhibits the uptake of serotonin by neurons, which increases serotonin levels in the synaptic cleft and allows it to bind to postsynaptic receptors. Norfluoxetine is a metabolite of fluoxetine and its pharmacological effects are similar to those of fluoxetine. It has been shown that norfluoxetine inhibits the binding of 5-hydroxytryptamine (5-HT) to 5-HT1A receptors. Norfluoxetine is also used as an analytical method for quantifying 5-HT concentrations in cells and tissues.Formule :C16H17ClF3NODegré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :331.76 g/mol17,21Dihydroxy-16β-methylpregna-1,4,9(11)-triene-3,20-dione
