Finnzymes' Direct PCR – forget DNA purification

Finnzymes’ novel approach, Direct PCR, saves you time and cost by allowing amplification of DNA directly from the source material. Direct PCR is based on Finnzymes' Phusion® High-Fidelity DNA Polymerases and Phire® Hot Start II DNA Polymerase. These unique fusion enzymes have been engineered to incorporate a double-stranded DNA binding domain that gives them extraordinary properties. Phusion and Phire DNA Polymerases are exceptionally tolerant of many PCR inhibitors present in various sample material. This allows robust amplification in conditions where conventional DNA polymerases, like Taq or Pfu, are completely inhibited.

See the product page for examples and additional information. List of plant materials tested with Phire Plant Direct PCR Kit (updated March 2010)
PCR directly from blood
		Phusion® Blood Direct PCR Kit is designed for amplification of DNA directly from whole blood. See the product page for examples and additional information. Application note: Direct PCR from blood preserved on Whatman FTA® and 903® Cards Application protocol: PCR-RFLP directly from blood using Phusion® Blood Direct PCR Kit

Note that PCR from unpurified starting material may require more optimization than standard PCR reactions from purified DNA. Also, the Direct PCR approach may not be suitable for all applications. So, please read the protocols carefully when planning your Direct PCR experiments. If you have questions or comments, please don't hesitate to contact us or your local distributor.
