Applied Biosystems® AmpliTaq Gold® DNA Polymerase, LD (Low DNA) is a highly purified version of AmpliTaq Gold® DNA Polymerase that significantly reduces contaminating bacterial DNA sequences commonly present in recombinant protein preparations.

• Manufacturing process results in highly purified enzyme with lower levels of bacterial DNA
• Minimizes non-target, false positive PCR products when amplifying bacterial sequences
• Chemically modified hot-start technique eliminates biological contamination
• GeneAmp® 10X PCR Gold Buffer promotes faster enzyme activation and robust PCR amplification
• Enhanced specificity with time-release PCR is ideal for low-copy target amplification
• AmpliTaq Gold® DNA Polymerase, LD improves both yield and success rate for target amplification

Reliable Results
This highly purified enzyme preparation gives you more confidence in your results and makes advanced PCR techniques quick and easy. When combined with the supplied GeneAmp® 10X PCR Gold Buffer, AmpliTaq® Gold DNA Polymerase, LD provides a flexible hot-start system that is suitable for all PCR applications that require the elimination of bacterial DNA contamination.
