5-Carboxy-X-rhodamine, succinimidyl ester
CAS :<p>Single isomer of 5(6)-ROX. It is a fluorescent dye used in RT-PCR methods as an internal reference to determine fluorescence variation that is not associated with the amplification process (plastic of the wells, small differences in concentration or volume, instrument measurements). It produces a constant fluorescence emission signal during the PCR process that is used to normalise the emission produced by the reporter. The fluorescence signal is compatible with that of most reporters. It is used to label the 5â end of oligonucleotides as a reporter in the presence of a quencher at the 3â end (dual labelled probe). During amplification, the dye is cleaved, and the fluorescence increases proportionally with the amount of the specific sequence amplified during the PCR process. The development of the fluorescence signal is therefore specifically related to the amplification of the target sequence. 6-ROX with NHS-activated carboxylic acids reacts with primary amines.</p>Formule :C37H33N3O7Degré de pureté :Min. 95%Couleur et forme :Red To Violet To Black SolidMasse moléculaire :631.67 g/molDimidium bromide
CAS :<p>Dimidium bromide is a cationic surfactant that is used in detergent compositions. It is a magnesium salt of a fatty acid and has been shown to be effective against infectious diseases when it is used to clean contaminated surfaces. Dimidium bromide has been shown to be an effective antimicrobial agent, even in the presence of benzalkonium chloride, which is an inhibitor of antimicrobial agents. When dimidium bromide is combined with nitrogen atoms, it can enhance the antimicrobial activity against resistant bacteria. This compound also shows anti-inflammatory properties and can be used for wastewater treatment as well as for cell culture.</p>Formule :C20H18BrN3Degré de pureté :Min. 95%Couleur et forme :Red PowderMasse moléculaire :380.28 g/molSolvent yellow 2

CAS :<p>Tetranitroblue tetrazolium chloride (TNBT) is a reagent that is used to measure the activity of enzymes in biological samples. TNBT can be used as a histological stain for myocardial infarcts and other areas of necrosis. It has been shown to be reactive with toll-like receptors, which are proteins that play a role in the immune response. The reaction mechanism of TNBT starts with its conversion to blue formazan crystals by peroxidase or other oxidizing enzymes. These crystals are reduced back to their original colorless form by reducing agents such as NADH or glutathione, which are present in most cells. This reduction process generates an electron that is then transferred to NAD+, forming NADH and releasing H2O2 as a byproduct.</p>Formule :C40H28Cl2N12O10Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :907.63 g/molTetrazolium blue chloride
