CAS :<p>5-(6)-Carboxytetramethylrhodamine (TAMRA) is a fluorescent dye that is used as a probe for DNA-based analysis. It binds to the 5' end of dsDNA, forming an intrastrand duplex. The fluorescence of TAMRA increases when it binds to dsDNA and can be used as a measure of the amount of DNA in a sample. TAMRA has been shown to be useful in the diagnosis of bowel disease and in the investigation of gene expression during body formation. This dye is also used as a marker for covalent linkages and high molecular weight proteins such as cyclin D2.</p>Formule :C25H22N2O5Degré de pureté :Min. 95 Area-%Couleur et forme :Red PowderMasse moléculaire :430.45 g/molLuminol HCl

CAS :<p>Thiazolyl blue tetrazolium bromide, also called 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide and methylthiazolyldiphenyl-tetrazolium bromide, and mainly known as MTT, is employed in the so-called MTT reduction or colorimetric assay. The MTT assay is used to determine the metabolic activity of living cells and the viable cell number in proliferation and cytotoxicity studies. The assay is based on the enzymatic reduction of the yellow MTT to the purple-blue water-insoluble formazan catalysed by mitochondrial dehydrogenases of living cells. The amount of formazan produced is directly proportional to the number of viable cells and can be quantified by measuring absorbance at 570nm. The MTT assay is broadly employed in cell biology because it is rapid and economical. MTT is also used as enzyme substrates in studies of nicotinamide adenine dinucleotide phosphate (NADP)-dependent dehydrogenases.</p>Formule :C18H16BrN5SDegré de pureté :Min. 97 Area-%Couleur et forme :Yellow PowderMasse moléculaire :414.32 g/mol6-NBDG

It also inhibits neuronal death induced by receptor activity. Ruthenium red has been shown to have inhibitory properties against p-nitrophenyl phosphate, an activator of protein kinase C and a stimulator of mitochondrial permeability transition. Ruthenium red has also been shown to inhibit dinucleotide phosphate-dependent phosphohydrolases and ryanodine receptors. Furthermore, it binds to nuclear DNA in prokaryotic cells and affects gene transcription.</p>Formule :H42Cl6N14O2Ru3Degré de pureté :Min. 98%Couleur et forme :PowderMasse moléculaire :786.35 g/mol4-Dimethylaminocinnamaldehyde
CAS :<p>4-Dimethylaminocinnamaldehyde (DMAC) is a metabolite of the herbicide paraquat. It has been studied as an anticancer agent that inhibits the proliferation of human carcinoma cell lines and induces apoptosis. DMAC also binds to DNA, inhibiting transfer reactions and preventing the synthesis of unsymmetrical dyes and procyanidins. DMAC has been shown to inhibit inflammation in mice by blocking the production of prostaglandins and leukotrienes. The anti-inflammatory activity is due to its ability to inhibit cyclooxygenase (COX) enzymes, thereby preventing the formation of prostaglandins from arachidonic acid.</p>Formule :C11H13NOCouleur et forme :Yellow PowderMasse moléculaire :175.23 g/molWST-5
