  • Patent number: 8247179
    Abstract: This invention provides for compositions for use in real time nucleic acid detection processes. Such real time nucleic acid detection processes are carried out with energy transfer elements attached to nucleic acid primers, nucleotides, nucleic acid probes or nucleic acid binding agents. Real time nucleic acid detection allows for the qualitative or quantitative detection or determination of single-stranded or double-stranded nucleic acids of interest in a sample. Other processes are provided by this invention including processes for removing a portion of a homopolymeric sequence, e.g., poly A sequence or tail, from an analyte or library of analytes.

  • Patent number: 8133989
    Abstract: This invention provides novel processes for amplifying nucleic acid sequences of interest, including linear and non-linear amplification. In linear amplification, a single initial primer or nucleic acid construct is utilized to carry out the amplification process. In non-linear amplification, a first initial primer or nucleic acid construct is employed with a subsequent initial primer or nucleic acid construct. In other non-linear amplification processes provided by this invention, a first initial primer or nucleic acid construct is deployed with a second initial primer or nucleic acid construct to amplify the specific nucleic acid sequence of interest and its complement that are provided. A singular primer or a singular nucleic acid construct capable of non-linear amplification can also be used to carry out non-linear amplification in accordance with this invention.

  • Patent number: 8097405
    Abstract: A process for determining the sequence of nucleic acids of interest employs nucleotides or nucleotide analogs that have been made detectable by non-radioactive modifying or labeling. Such nucleotides or nucleotide analogs are modified on the sugar moieties, the phosphate moieties or the base moieties, including base analogs. Modified nucleotide analogs can be attached to or coupled to or incorporated into DNA or RNA. The modified or labeled nucleotides or nucleotide analogs are also useful in processes for detecting the presence of nucleic acids of interest and for characterizing chromosomal sequences. Detection processes using the modified or labeled nucleotides or nucleotide analogs extend to the use of a gel for separating or resolving hybrids formed between non-radioactively labeled oligonucleotides or polynucleotides and such nucleic acids of interest.

  • Publication number: 20110097791
    Abstract: This invention provides inter alia an in vitro process for producing multiple specific nucleic acid copies in which the copies are produced under isostatic conditions, e.g., temperature, buffer and ionic strength, and independently of any requirement for introducing an intermediate structure for producing the copies. In other aspects, the invention provides in vitro processes for producing multiple specific nucleic acid copies in which the products are substantially free of any primer-coded sequences, such sequences having been substantially or all removed from the product to regenerate a primer binding site, thereby allowing new priming events to occur and multiple nucleic acid copies to be produced. This invention further provides a promoter-independent non-naturally occurring nucleic acid construct that produces a nucleic acid copy or copies without using or relying on any gene product that may be coded by the nucleic acid construct.

  • Patent number: 7713528
    Abstract: This invention relates to novel reagent conjugates and a novel multi-step process for delivering active compounds to target analytes of interest in a patient for diagnostic and therapeutic purposes. According to the process, two novel reagents are bound to each other by linkage of the sequence-specific components they contain. The first reagent, which is comprised of a target recognition component and a first sequence-specific component, is introduced into the patient and allowed to achieve maximal localization on the target cells. The second reagent, which is comprised of an active compound component and a second sequence-specific component is then introduced into the patient, thereby forming a complex with the first reagent via the recognition and binding of the sequence-specific components of the two reagents to form the reagent conjugate of the invention. The active compound component is thereby efficiently and specifically delivered to the target analyte.
