Descripción

General description

AccuTaq^™ long and accurate (LA) DNA Polymerase is a combination of Taq DNA polymerase with a small amount of a polymerase with the 3′→5′ exonuclease activity necessary for proofreading. It enables the amplification of genomic targets larger than 20 kb. This blend increases the length of amplification products by using the proofreading polymerase to repair terminal misincorporations. This repair enables the polymerase to resume elongating the growing DNA strand. After the proofreading activity, the final products mostly have a blunt end.

Application

AccuTaq^™ LA DNA Polymerase produces long DNA amplicons for:

• Mutation analysis
• Cloning genes
• DNA sequencing
• cDNA library generation
• Polymerase chain reaction (PCR)
• Direct PCR

Features and Benefits

• Increased fidelity, up to 6.5× that of Taq DNA polymerase
• Efficiently and accurately produce amplicons up to 22 kb on genomic templates and up to 40 kb on less complex templates such as lambda or bacterial DNA.

Packaging

The enzyme is provided with an optimized 10× reaction buffer for enhanced amplification of complex templates. A separate vial of DMSO is included. Addition of DMSO in the reaction at a final concentration of 1-4% may increase yield and improve reliability of the system with some complex PCR targets.

Other Notes

AccuTaq LA DNA polymerase is an optimized blend of Sigma′s high quality Taq DNA polymerase and a small amount of an additional polymerase that exhibits 3′→5′ exonuclease or proofreading activity. By blending the Taq with the right amount of this proofreading enzyme, misincorporation errors are corrected, producing PCR amplicons that are longer and more accurate.

Store AccuTaq LA DNA Polymerase and the 10x Buffer at –20 °C. Store DMSO at room temperature. Melting frozen DMSO at ~30 °C will not affect performance.

One unit incorporates 10 nmol of total dNTPs into acid-precipitable DNA in 30 min. at 74°C.
