Paper cards are a popular method of storing blood due to their ease of use and long term stability at room temperature.
However, these cards often contain various chemicals that may inhibit enzymatic reactions, and thus special extraction buffers and/or protocols are generally recommended before such samples can be used in PCR.
Phusion Blood DNA Polymerase is an engineered hot start enzyme based on fusion protein technology that contains a dsDNA binding domain which allows efficient amplification of DNA even in the presence of a wide range of inhibitors, including those found in blood and in storage cards.
