Applied Biosystems® AmpliTaq® DNA Polymerase, LD (Low DNA), is the same enzyme as AmpliTaq® DNA Polymerase, but is further purified through a proprietary separation process to ensure that residual bacterial DNA sequences are substantially reduced.

Manufacturing process results in highly purified enzyme with lower levels of bacterial DNA

• Minimizes non-specific PCR products when amplifying bacterial targets
• Highly purified enzyme making it particularly useful for low copy number amplifications

This highly purified enzyme preparation ensures that non-target, false-positive PCR products will be effectively minimized when amplifying bacterial sequences. This is especially useful for low-copy-number PCR amplifications. The enzyme is quality-control tested to verify that fewer than 10 copies of bacterial 16S ribosomal RNA gene sequences are present in a standard 2.5 unit aliquot. AmpliTaq® DNA Polymerase, LD is supplied with GeneAmp® 10X PCR Buffer I. It is also available with GeneAmp® 10X PCR Buffer II and MgCl2 Solution.
