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.

Abstract: Energy transfer dye pairs including a donor dye covalently attached to an acceptor dye through a linker, uses of the energy transfer dye pairs, for example, in conjugates of an energy transfer dye pair covalently attached to a quencher and an analyte (e.g., an oligonucleotide), for biological applications including, for example, amplification assays such as quantitative polymerase chain reaction (qPCR) and digital PCR (dPCR).

Abstract: A composition is provided comprising a negatively charged group, an oligonucleotide sequence and at least none or one nuclease-resistant linkage group to form a chemically-enhanced primer. The chemically-enhanced primer can be used for sequencing and fragment analysis. Methods for synthesizing the primer as well as a method of preparing DNA for sequencing and 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 under conditions in which excess amplification primer is degraded by the nuclease and the chemically-enhanced primer is essentially non-degraded.

Abstract: A system (1000) comprising first and second excitation sources (101a, 101b) with respective excitation wavelengths for exciting first second and third dyes in a sample (110) and further comprising a detector (115), first and second emission spectral elements (121a, 121b) for transmitting respective first and second emission wavelengths as well as a processor (130) for automatically operating the elements of the system. The first dye comprises a first absorption spectrum comprising a first maximum absorption wavelength and the second dye comprises a second absorption spectrum comprising a second maximum absorption wavelength that is equal to or substantially equal to the first maximum absorption wavelength. The second dye comprises a second emission spectrum comprising a second maximum emission wavelength and the third dye comprises a third emission spectrum comprising a third maximum emission wavelength that is equal to or substantially equal to the second maximum emission wavelength.
