Abstract
A chemically-enhanced primer is provided comprising a negatively charged moiety (NCM), an oligonucleotide sequence having a) non-nuclease resistant inter-nucleotide linkages or b) at least one nuclease resistance inter-nucleotide linkage. The chemically-enhanced primer can be used for sequencing and fragment analysis. Methods for synthesizing the chemically-enhanced primer as well as a method of preparing DNA for sequencing, a method of sequencing DNA, and kits containing the chemically-enhanced primer are also provided. The method of sequencing DNA can comprise contacting amplification reaction products with the composition wherein excess amplification primer is degraded by the nuclease and the chemically-enhanced primer is essentially non-degraded.
