Hieff Double-Block Anti-Taq DNA Polymerase Antibody is a double-blocking Taq DNA Polymerase monoclonal antibody for hot start PCR. It can inhibit the activity of 5 `- 3` polymerase and 5 `- 3` exonuclease after binding to Taq DNA Polymerase, which can effectively inhibit the nonspecific annealing of primers and the nonspecific amplification caused by primer dimer at low temperatures. In addition, the product can effectively prevent probe degradation. HieffTM Double-Block anti-Taq DNA Polymerase Antibody is denatured in the initial DNA denaturation step of PCR reaction, through which the activity of DNA polymerase is restored to achieve the effect of hot start PCR. It can be used under the condition of routine PCR reaction without special inactivation of antibodies.

UltraNuclease, also known as a non-restrictive endonuclease, broad-spectrum nuclease, is a non-specific endonuclease derived from Serratia Marcescen, which hydrolyzes internal phosphodiester bonds between any nucleotides in nucleic acids to produce 5`-monophosphate oligonucleotides of 2-5 bases in length. It can degrade DNA and RNA in various forms (double-stranded, single-stranded, linear, circular, native or denatured) under a very broad range of conditions (6 M Urea, 0.1 M Guanidine HCl, 0.4% Triton X-100, 0.1% SDS, 1 mM EDTA, 1 mM PMSF) and is widely used to remove nucleic acids from biological products.  UltraNuclease can also be removed by corresponding methods subsequently.

The NTP Set Solution is a convenient set of 100 mM aqueous solutions of each of ATP, CTP, UTP, and GTP, supplied in separate vials.

CTP solution (100 mM) is a transparent colorless aqueous solution prepared from CTP trisodium salt, and free from DNase, RNase, and phosphatase contamination.
