Quantitation of DNA Sequences in Environmental PCR Products by a Multiplexed, Bead-Based Method

Received 14 August 2001/ Accepted 29 November 2001

A first application of a multiplexed, bead-based method is described for determining the abundances of target sequences in an environmental PCR product. Target sequences as little as 0.3% of the total amount of DNA can be quantified. Tests were conducted on 16S ribosomal DNA sequences from microorganisms collected from contaminated groundwater.
