  • Publication number: 20200239878
    Abstract: Described herein are methods and compositions that provide highly efficient nucleic acid amplification. In some embodiments, this allows a 3-fold or greater increase of amplification product for each amplification cycle and therefore increased sensitivity and speed over conventional PCR. Modified bases can be employed in primers to provide this base-3 or greater amplification with satisfactory PCR cycle times, which are improved, as compared to those observed in the absence of modified bases.

  • Patent number: 10724083
    Abstract: Provided are methods and compositions for activating oligonucleotide aptamer-deactivated DNA polymerases, comprising cleaving the aptamer by endonuclease V enzymatic activity to reduce or eliminate binding of the oligonucleotide aptamer to the DNA polymerase, thereby activating DNA synthesis activity of the DNA polymerase in a reaction mixture. Mixtures for use in methods of the invention are also provided. In some aspects, the oligonucleotide aptamer comprises one or more deoxyinosine nucleotides providing for aptamer-specific recognition and cleavage of the aptamer by the endonuclease V enzymatic activity. Exemplary oligonucleotide aptamers, mixtures and methods employing endonuclease V enzymatic activity are provided. The methods can be practiced using kits comprising a DNA polymerase-binding oligonucleotide aptamer and at least one endonuclease V enzymatic activity having oligonucleotide aptamer-specific recognition to provide for specific cleavage of the aptamer by the endonuclease V enzymatic activity.

  • Patent number: 10348225
    Abstract: A DC electric motor having a stator mounted to a substrate, the stator having a coil assembly having a magnetic core, a rotor mounted to the stator with permanent magnets distributed radially about the rotor, the permanent magnets extending beyond the magnetic core, and sensors mounted to the substrate adjacent the permanent magnets. During operation of the motor passage of the permanent magnets over the sensors produces a substantially sinusoidal signal of varying voltage substantially without noise and/or saturation, allowing an angular position of the rotor relative the substrate to be determined from linear portions of the sinusoidal signal without requiring use of an encoder or position sensors and without requiring noise-reduction or filtering of the signal.
