Sigma Aldrich Fine Chemicals Biosciences fastStartTM High fidelity
The fastStart(TM) High fidelity PCR System is a blend of fastStart Taq DNA Polymerase and a thermostable proofreading protein which is also chemically modified. This protein mediates proofreading activity but carries no polymerase activity. Both proteins are inactive below 75 C and are activated by heating to 95 C for two minutes.Hot start protocols have improved specificity sensitivity and PCR yield. Heat-labile blocking groups on amino acid residues of fastStart(TM) Taq DNA Polymerase make the enzyme inactive at room temperature. There is no elongation at low temperatures when primers bind nonspecifically. fastStart(TM) Taq DNA Polymerase is activated by removal of blocking groups using a preincubation step at 95C. The fastStart(TM) High fidelity PCR System is the product of choice for multiplex PCR. fastStart(TM) High fidelity Enzyme Blend (5 U/mul) in storage bufferfastStart(TM) High fidelity Reaction Buffer 10x concentrated with 18 mM MgCl2fastStart(TM) High
Sigma Aldrich Fine Chemicals Biosciences CfTM 633 succinimidyl este
far-red fluorescent dyes offer the advantage of ultra sensitive detection because background signal due to autofluorescence in most biological samples is minimal in this spectral region. for many years the cyanine dye Cy(R)5 has been the dye of choice for such detection. More recently Alexa fluor(R) 647 has been developed as a better alternative by having brighter fluorescence and higher photostability. Despite the improvement Alexa fluor(R) 647 still lacks sufficient photostability required for many demanding applications. On the other hand while Alexa fluor(R) 633 is photostable its fluorescence on proteins is very weak. In fact it has been a challenging task for dye chemists to develop a far-red fluorescent dye that is both highly fluorescent and photostable for protein and nucleic acid labeling. Using new chemistry scientists at Biotium have successfully developed a series of far-red and near-IR dyes to overcome these challenges. With its absorption peak at 630 nm Cf(TM)633
Sigma Aldrich Fine Chemicals Biosciences Glyceraldehyde 3 phosphate
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) localizes to the cytoplasm but can be translocated to the nucleus depending on cellular conditions. It is a tetramer containing identical chains. The gene encoding GAPDH is localized on human chromosome 12p13.

Sigma Aldrich Fine Chemicals Biosciences Denaturation Solution for
Sigmas denaturing SOLUTIONon is a strong base that denatures double-stranded DNA so that it can be efficiently transferred to nylon membrane and subsequently hybridized to labeled probe. When used with a depurination SOLUTIONon treatment results in the hydrolysis of the phosphodiester backbone at the sites of depurination allowing for more efficient transfer of large DNA in neutral Southern transfers.
