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

The use of Laemmli sample buffer ensures optimal band resolution when preparing proteins for SDS-PAGE with Tris-glycine-SDS running buffer. Role of 5X SDS PAGE Sample buffer :1. Tris is a buffer and it’s pH plays an essential role in preserving peptide bonds from breaking apart. 2. Sodium dodecyl sulphate is an anionic detergent that helps in linearizing (by denaturing) the proteins and bringing a net negative charge to the proteins irrespective of the initial charge. 3. The high density of glycerol ensures the sample moves down into the well. 4. Beta-mercaptoethanol, along with SDS, ensure the bands are individual polypeptide instead of molecular complexes. 5.

The pH play an essential role in preserving peptide bonds from breaking apart. SDS: Proteins comes in different sizes and charges. SDS is an anionic detergent that helps in linearizing (by denaturing) the proteins and bringing a net negative charge to the proteins irrespective of the initial charge. Glycerol: The high density (thickening of the solution) of glycerol ensures the sample moves down into the well. DL-Dithiothreitol (DTT): is a strong reducing agent. Its specific role in sample denaturation is to remove the last bit of tertiary and quaternary structure by reducing disulfide bonds.
