Abstract: Provided are nucleic acid molecules which comprise at least a portion of a polymorphic genetic marker for determining whether a canine has a mutated progressive rod-cone degeneration disease (prcd) gene locus in one or both alleles. The genetic markers are located on canine chromosome 9 in a genomic region identified as the prcd-informative region. A method for making genetic markers representing polymorphic sequences located in the prcd-informative region of canine chromosome 9 comprises isolating a polymorphic DNA sequence in the prcd-informative region, using oligonucleotides complementary with at least a portion of the sequence to amplify the sequence, and analyzing canine chromosome 9 in a prcd-informative pedigree for the ability of the polymorphic sequence to co-segregate with the prcd gene locus by a linkage test.

Abstract: An improved nucleic acid hybridization process is provided which employs a modified oligonucleotide and improves the ability to discriminate a control nucleic acid target from a variant nucleic acid target containing a sequence variation. The modified probe contains at least one artificial mismatch relative to the control nucleic acid target in addition to any mismatch(es) arising from the sequence variation. The invention has direct and advantageous application to numerous existing hybridization methods, including, applications that employ, for example, the Polymerase Chain Reaction, allele-specific nucleic acid sequencing methods, and diagnostic hybridization methods.
Abstract: A process and an apparatus for continuously and efficiently producing high protein foodstuff such as cheese curd, by continuously sprinkling and pouring a protein solution such as cow's milk or soybean milk from above onto the water surface of a warm water bath through a nozzle having multiple holes. A constant amount of warm water kept at a fixed temperature is supplied to the water bath. This process converts the protein solution into curd useful in producing various types of cheese.
Abstract: The invention is based on the discovery that adults having a genotype comprising a hemoglobin .alpha.-gene deletion are significantly more likely to be hypertensive than adults having a normal (.alpha..alpha./.alpha..alpha.) gentoype. The invention provides an improved method for determining a human subject's genotype at the .alpha.-gene loci; a method of screening a human subject for an increased potential of developing hypertension and other blood-related disorders; and provides an apparatus/kit for screening a human subject for a risk of developing hypertension and other blood-related disorders.
Abstract: Primers and methods for adapter-mediated multiplex amplification of the IS6110 insertion element of Mycobacterium tuberculosis (M.tb) and the 16S ribosomal gene of Mycobacterium tuberculosis, useful for simultaneously detecting and/or identifying species of the M. tuberculosis complex and other clinically relevant Mycobacterium species. Multiplex Strand Displacement Amplification (SDA) is used in a single amplification reaction which is capable of simultaneously identifying M. tuberculosis and providing a screen for substantially all of the clinically relevant species of Mycobacteria. Also disclosed are methods for adapter-mediated multiplex amplification of multiple target sequences and a single internal control sequence for determination of sample efficacy or quantitation of the targets.

Abstract: A new approach is proposed for sequencing by hybridization (SBH), which uses interaction to dramatically reduce the number of oligonucleotides used for de novo sequencing of large DNA fragments, while preserving the parallelism which is the primary advantage of SBH. In particular, a series of rounds is performed, starting from an initial fixed oligonucleotide array, of hybridizing a target sample against an array, and then designing a new oligonucleotide array in response to the results of the rounds to date, until the sequence is determined.
