Opis

Opis ogólny

Contents
Taq DNA Polymerase, 5 U/μl
PCR Buffer, 10x concentrated, with MgCl₂
PCR Nucleotide Mix

For maximum convenience, select the ready-to-use 2x concentrated PCR Master.

Each dNTPack contains 10 mM additive-free sodium salt nucleotides as a ready-to-use mix.

Taq DNA Polymerase is a highly processive 5′→3′ DNA polymerase that lacks 3′→5′ exonuclease activity. It is a single polypeptide chain with a molecular weight of approximately 95 kDa.
Taq DNA Polymerase was originally isolated from the thermophilic eubacterium Thermus aquaticus BM, a strain lacking Taq I restriction endonuclease. The enzyme preparation obtained from E.coli is free of nonspecific engo- or exonucleases according to the current quality control procedures.

Zastosowanie

Achieve the most consistent results in simple, routine PCR by using Roche Applied Science Taq DNA Polymerase, which is held to our rigorous purity and quality standards. The Taq DNA Polymerase, dNTPack, combines our standard preparation (5 U/μl) of recombinant Taq DNA Polymerase with our convenient, ready-to-use PCR Nucleotide Mix. In all other respects, this preparation is identical to our standard preparation and can be used for:

• PCR[1]
• RT-PCR
• Other primer-extension reactions, such as sequencing and labeling

Cechy i korzyści

• Reliable reproducible results: High lot-to-lot consistency.
• No need to test each lot: Taq DNA Polymerase is rigorously tested.
• Prevent PCR carryover: dUTP incorporation combination with Uracil-DNA Glycosylase prevents PCR cross-contamination.

Opakowanie

1 kit containing 3 components

Jakość

Each lot is PCR tested using λDNA. Each lot is also tested for the absence of exo- and endonucleases, and nicking activities according to the current Quality Control procedures.

Definicja jednostki

One unit Taq DNA Polymerase is defined as the amount of enzyme that incorporates 10 nmol of total deoxyribonucleosidetriphosphates into acid precipitable DNA within 30 minutes at +75 °C under the assay conditions stated under unit assay.

Unit Assay: Incubation buffer:
67 mM Tris/HCl; pH 8.3/25 °C, 5 mM MgCl₂, 10 mM Mercaptoethanol, 0.2% Polydocanol, 0.2 mg/ml Gelatine, 0.2 mM each dATP, dGTP, dTTP and 0.1 mM dCTP.

Incubation procedure:
M13mp9ss, M13 primer (17mer) and 1 μCi (α^-32P) dCTP are incubated with suitable dilutions of Taq DNA Polymerase in 50 μl incubation buffer at +65 °C for 60 minutes. The amount of incorporated dNTPs is determined by trichloroacetic acid precipitation.

Volume Activity: 5 U/μl

Przechowywanie i stabilność

Containers which are opened must be carefully resealed and
kept upright to prevent leakage

Inne uwagi

For life science research only. Not for use in diagnostic procedures.

Routine assays have medium size amplicons and 50% GC content. Taq DNA Polymerase has no proofreading or hot start features. It is optimally active at +75°C and pH 9.

Lack of restriction endonuclease:
The enzyme originally isolated from T. aquaticus BM lacks Taq I restriction endonuclease activity.
