The new Expand Long Range dNTPack of Roche Applied Science is a robust solution to consistently amplify long PCR products, which kits from other suppliers are often not able to amplify
The dNTPack is a second generation product to the well-known Expand Long Template PCR System.
It contains a sophisticated blend of thermostable DNA polymerases, an optimised buffer system, and ultrapure PCR-Grade Nucleotides.
The Expand Long Range dNTPack is optimised to efficiently amplify large genomic DNA fragments from 5kb to 25kb in combination with a threefold higher fidelity compared to Taq DNA Polymerase.
It is ideally suited for genome mapping and sequencing, contig construction, characterisation of cloned sequences in lambda phages or cosmids, and eukaryotic-gene cloning and analysis.
It also allows the rapid identification and cloning of complete genes from genomic DNA using cDNA sequence information as a starting point.
PCR success is highly dependent on the selection of both nucleotides and enzymes.
To ensure the best PCR results, dNTPacks combine both in one economical package.
