1. A method for enzymatically amplifying a target nucleic acid or a fragment thereof, comprising(a) providing a nucleic acid amplification reaction mixture that comprises (i) a target nucleic acid, and (ii) gellan at a concentration above 0.005 wt % based on the weight of water;
- and(b) subjecting the nucleic acid amplification reaction mixture of (a) to conditions suitable for amplifying the target nucleic acid or a fragment thereof, whereby the target nucleic acid or the fragment thereof is amplified.

Abstract
A method is provided for nucleic acid amplification with enhanced sensitivity. The method for enhanced sensitivity involves carrying out the amplification reaction in the presence of gellan. For instance, the method allows for the production of detectable amounts of PCR amplified DNA from at least 10 fold fewer target molecules than a comparable PCR reaction in absence of gellan.
