Patent number: 7511127Abstract: Provided herein are methods to discover and use single nucleotide polymorphisms (SNP) for identifying breed, or line and breed, or line composition of a bovine subject. The present invention further provides specific nucleic acid sequences, SNPs, and SNP patterns that can be used for identifying breed or breed combinations for Angus, Holstein, Limousin, Brahman, Hereford, Simmental, Gelbvieh, Charolais and Beefmaster breeds.

Patent number: 7378242Abstract: A novel limited primer extension reaction improves detection sensitivity and specificity in a variety of hybridization platforms. In the invention, a sequence of target DNA that lacks one of the four types of nucleic acid bases for a span of eight or more adjacent nucleotide positions is selected for use. This sequence is referred to as the extension complement sequence, or ECS. A primer with a sequence that is complementary to the target sequence that is immediately downstream (to the 3? side) of this ECS is used to initiate an extension reaction. Extension occurs using a DNA polymerase and standard deoxynucleoside triphosphates for three of the four types of nucleic acid bases. The fourth base, which is complementary to the base missing in the ECS, is either absent or present only in the form of a dideoxynucleoside triphosphate, which does not support further extension. In either case, the extension reaction does not proceed past the first occurrence in the template of the base that is missing in the ECS.Type: GrantFiled: March 17, 2005Date of Patent: May 27, 2008Assignee: Atom Sciences, Inc.Inventor: Richard A. Hurt

Patent number: 7374885Abstract: The present invention is directed to novel methods of synthesizing multiple copies of a target nucleic acid sequence which are autocatalytic (i.e., able to cycle automatically without the need to modify reaction conditions such as temperature, pH, or ionic strength and using the product of one cycle in the next one). In particular, the present invention discloses a method of nucleic acid amplification which is robust and efficient, while reducing the appearance of side-products. The method uses only one primer, the “priming oligonucleotide,” a promoter oligonucleotide modified to prevent polymerase extension from its 3?-terminus and, optionally, a means for terminating a primer extension reaction, to amplify RNA or DNA molecules in vitro, while reducing or substantially eliminating the formation of side-products. The method of the present invention minimizes or substantially eliminates the emergence of side-products, thus providing a high level of specificity.Type: GrantFiled: August 26, 2005Date of Patent: May 20, 2008Assignee: Gen-Probe IncorporatedInventors: Michael M. Becker, Wai-Chung Lam, Kristin W. Livezey, Steven T. Brentano, Daniel P. Kolk, Astrid R. W. Schroder

Patent number: 7335471Abstract: Mutant RNA polymerases of phagic origin in which the peptide chain is modified by substitution, deletion or addition of at least one amino acid, the modification having the effect of reducing the sensitivity of the RNA polymerases to the initial transcription sequence of the DNA sequence coding for the RNA, for a method for production of the RNA, or proteins coded by the RNA, from given nucleotide sequences, comprising a sequence of DNA coding for the RNA, the transcription of which is placed under the control of a promoter recognised by wild-type RNA polymerases and the mutant RNA polymerases as above.
