The KAPA HiFi HotStart PCR Kit contains an engineered B-family (proofreading) DNA polymerase and uniquely-formulated buffers, and requires specialized reaction conditions. Endpoint PCR protocols that evaluated other Hot Start DNA polymerases all employed 1.25 U of DNA polymerase, five copies of HIV recombinant DNA (as standardized from the Gene Amplimer kit), 10 ng of human genomic DNA as a carrier, 0.2 mM dNTPs, in a 50 μl reaction volume. STORAGE. Equal volumes of the reaction were analyzed on a 2% agarose gel. Ask for SureStart Taq DNA polymerase, the hot start product that integrates into PCR protocols optimized with Taq DNA polymerase - with little or no modification of cycling parameters or reaction conditions. A 2 kb fragment of human β-globin gene was amplified with different hot-start PCR master mixes. A Hot Start thermal activation step removes the modification and generates the corresponding unmodified primer, which supports amplification of the desired target. that allow for primer-based Hot Start activation in PCR (1). Since the inception of Hot Start as a means of blocking DNA polymerase extension at lower temperatures, a number of approaches have been developed that target the essential reaction components such as magnesium ion, DNA polymerase, oligonucleotide primers, and dNTPs. TaKaRa LA Taq DNA Polymerase Hot-Start Version consists of Takara LA Taq polymerase plus a monoclonal antibody. The Master Mix simplifies PCR set-up, offering time savings, consistency, and minimal risk of contamination. Notice to Purchaser This enzyme is specifically optimized for increasing base incorporation rate by inactivating 5’->3’ exonuclease activity. Magnesium precipitate hot start method for PCR. The polymerase activity is restored during the initial denaturation step when the amplification reactions are heated at 94-95 degrees C for two minutes. The introduction of 4-oxo-tetradecyl (OXT) ph … If cloning is the next step, then blunt-end cloning is recommended. 2002 Jun;16(3):167-71. It improves PCR amplification reactions by decreasing background noise and increasing amplification of desired products. Klicken Sie hier für weitere Informationen. 1. Concentration: 5x. von Ihnen verwendete NEB PCR Polymerase – fertig! This modification prevents primer extension at the lower temperatures of PCR set-up and manipulation. Author information: (1)DNA Polymerase Technology, Inc., St. Louis, MO 63104, USA. rockstart@klentaq.com For the amplification of HIV-1 gag gene, and other challenging targets, a simple new hot start PCR protocol is presented which consists simply and entirely of the buffer system. required for a PCR protocol, it is advisable to design primers suitable for a two-step PCR protocol, if possible.
