HotStarTaq DNA Polymerase. Hot-start enzyme from Supplier AII. Concentration: 5 units/µl Recombinant enzyme: Yes Substrate analogs: dNTP, ddNTP, dUTP, biotin-11-dUTP, DIG-11-dUTP, fluorescent-dNTP/ddNTP Extension rate: 2-4 kb/min at 72°C Half-life: 10 min at 97°C ; 60 min at 94°C
Hot Start Taq DNA Polymerase is a mixture of Taq DNA Polymerase and an aptamer-based inhibitor. This inhibitor is bound reversibly to the enzyme, inhibiting its polymerase activity at temperatures below 45°C. Once this temperature has been reached, the inhibitor releases the enzyme.
Most DNA polymerases (enzymes that make new DNA) work only at low temperatures. But at low temperatures DNA is tightly coiled, so the polymerases don’t stand much of a chance of getting at most parts of the molecules. 3. Taq polymerase. This is the enzyme that is in charge of replicating DNA.
The full process of DNA replication is comprised of the intricate and coordinated interplay of more than 20 proteins. In 1958, Arthur Kornberg and his colleagues separated DNA polymerase from E.Coli. DNA polymerase is the first known of the enzymes whose function is to promote the bond formation of the
DNA polymerase III binds a region about 30 nucleotides long upstream of the RNA primer, with the alpha subunit making contact 9 nucleotides upstream and the beta clamp making contact 22 nucleotides upstream [Reems95, Reems94].
DNA polymerase can extend the primer and incorporate deoxyadenosine 5?-[?-thio]triphosphate (dATP[?S]). The preceding section has highlighted enzyme-mediated isothermal detection of DNA or RNA. One of the limitations of enzyme-based methods is that sample quality and the presence of
Taq DNA Polymerase is a thermostable DNA Polymerase isolated from an E. coli strain that carries the Taq DNA polymerase gene. GenScript Taq DNA Polymerase has been formulated using GenScript’s proprietary technology. The enzyme can be shipped at room temperature or even 37°C A thermostable DNA polymerase was used in an in vitro DNA amplification procedure, the polymerase chain reaction. The enzyme, isolated from Thermus aquaticus, greatly simplifies the procedure and, by enabling the amplification reaction to be performed at higher temperatures, significantly improves the
DNA polymerases are enzymes that catalyze the template-directed synthesis of DNA. Over billions of years, they have evolved to have the speed, specificity DNA polymerases have been classified into evolutionary families based on an analysis of their amino acid sequences. Initially two decades ago
Enzyme – DNA polymerase. Nucleotides – needed to extend the primers by the enzyme. The cut fragments of DNA can be amplified using PCR The resulting DNA molecule is a hybrid of two DNA molecules – the interest molecule and the vector. In the terminology of genetics this intermixing of
replication, a complex enzyme called DNA polymerase moves along the DNA molecule, pairing nucleotides on each template strand with free complementary nucleotides. Because of the antiparallel nature of the DNA strands, new strand synthesis is different on each template.

Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to
