  • Methods of forming circular nucleic acid probes and uses thereof
    Patent number: 7358047
    Abstract: The present invention relates generally to a method of amplifying closed circular nucleic acid probes and, more particularly, to a method of amplifying closed circular nucleic acid probes by rolling circle amplification. The method of the present invention is useful in a range of applications involving the detection of nucleic acid sequences such as, but not limited to, the identification of genetic disorders, genetic variants or the presence of microbiological or viral agents.

  • Assay
    Publication number: 20030104376
    Abstract: The present invention relates generally to a method for identifying or otherwise detecting a nucleotide repeat region having a particular length in a nucleic acid molecule. Varying lengths of the repeat region at particular genetic locations represent nucleotide length polymorphisms. The present invention provides, therefore, a method for identifying a nucleotide length polymorphism such as associated with a particular human individual or animal or mammalian subject or for a disease condition or a predisposition for a disease condition to develop in a particular individual or subject. The method of the present invention is also useful for identifying and/or typing micro-organisms including yeasts and lower uni- and multi-cellular organisms as well as prokaryotic micro-organisms. The method of the present invention is further useful in genotyping subjects including humans.

  • Method
    Publication number: 20030039964
    Abstract: The present invention relates generally to a method for detecting a nucleic acid molecule having a particular nucleotide sequence. Such a nucleic acid molecule is generally referred to as the “target” sequence or molecule. The method of the present invention generally comprises the use of competitive priming of pre- or post-amplified nucleic acid molecules. The nucleic acid molecules subjected to such primer interrogation are generally immobilized to a solid support by hybridization of a target molecule to a primer anchored to a solid phase. Amplimer-mediated bridging of a particular primer, -labelled or unlabelled, is then used to detect the presence of a primer having a selected sequence. The method of the present invention is useful in a range of applications including inter alia diagnosis, nucleotide sequencing and the screening for nucleic acid-modifying molecules such as carcinogens.

  • Genetic manipulation of plants to increase stored carbohydrates
    Patent number: 5981838
    Abstract: The present invention relates to plants genetically modified to increase the level of stored carbohydrates in the plant, particularly during periods of high sink activity and low source activity through production of a glycosyl-transferase which catalyzes the formation of soluble glucans. The invention also relates to the genetic constructs used to produce the engineered plants and the method of producing the engineered plants.
