  • Publication number: 20110318811
    Abstract: Compositions and method for making and using a synthetic bovine DNase I are disclosed. More particularly, the sbDNase I of the present invention is a versatile enzyme that cleaves DNA nonspecifically to release 5?-phosphorylated nucleotides. The sbDNase I molecules of the present invention find particular use in a wide range of molecular biology applications, including: degradation of contaminating DNA after RNA isolation; RNA clean-up prior to, or in conjunction with, RT-PCR after in vitro transcription; identification of protein binding sequences on DNA (DNase I footprinting); prevention of clumping when handling cultured cells; tissue dissociation and creation of fragmented DNA for in vitro recombination reactions.

  • Patent number: 8020790
    Abstract: Improved ball mill disruption techniques. In different embodiments, disrupting particles that are not substantially spherical are used. In other embodiments, roughened disrupting particles are used. In other embodiments, larger disrupting particles are used. In each instance, improved disruption can be achieved.

  • Publication number: 20080274458
    Abstract: The invention relates to a method of determining the amount of a target nucleic acid sequence in a sample, the method comprising: obtaining multiple distinguishable amplicons of the target nucleic acid sequence, each comprising a distinguishing tag and a target portion; amplifying the amplicons in a single reaction volume; and detecting nucleic acids amplified from the amplicons. Detection of the distinguishable amplicons can be varied in each of the steps of the method, which expands the dynamic range of the nucleic acid quantification methods and improves the reliability and accuracy of the methods.

  • Publication number: 20080131886
    Abstract: The present disclosure relates to methods of DNA amplification with a first primer that has a random sequence of nucleotides at its 3? end and a generic sequence 5? of the random nucleotides, as well as a second primer with the generic sequence of the first primer. The disclosure further relates to a method of precipitating DNA on a solid medium to improve DNA amplification. In a preferred embodiment, the presently disclosed methods are used for high-throughput genotyping of DNA samples, such as bloodstains or trace amounts of DNA.

  • Publication number: 20080131878
    Abstract: Embodiments of the invention include methods of detecting one or more RNA by reverse transcribing one or more RNA target using one or more reverse transcription primer comprising in a 5? to 3? direction (i) a primer segment, (ii) a probe segment distinct from the primer segment, and (iii) a 3? target specific segment that anneals to a RNA target; amplifying one or more RNA from the reverse transcription reaction using a first amplification primer that anneals to the 3? end of a reverse transcribed RNA target and a second primer that anneals to a sequence complementary to the primer segment; and detecting amplification of a target nucleic acid.
