Abstract:
The invention provides novel mutations, mutation combinations or mutational profiles of HIV-1 reverse transcriptase and/or protease genes correlated with phenotypic resistance to HIV drugs. More particularly, the present invention relates to the use of genotypic characterization of a target population of HIV and the subsequent correlation of this information to phenotypic interpretation in order to correlate virus mutational profiles with drug resistance. The invention also relates to methods of utilizing the mutational profiles of the invention in databases, drug development, i.e., drug design, and drug modification, therapy and treatment design, clinical management and diagnostic analysis.
Abstract:
The discriminating capability of hybridization assays is increased by a combination of labelled primers which produce amplificates of one strand of a nucleic acid with a capture probe which is complementary to the same strand of the nucleic acid.
Abstract:
Methods and compositions are provided for objectively identifying: i) bovine animals having the genetic potential to produce beef that is marbled or tender, and ii) bovine carcasses whose beef is marbled or tender. The methods comprise extracting DNA from a sample obtained from a bovine animal or carcass, assaying for the presence of a DNA comprising a sequence, referred to hereinafter as a “genetic marker”, in the DNA sample. In one aspect, the genetic marker is a marker of marbling, and comprises the sequence set forth in SEQ ID NO. 1. In another aspect, the genetic marker is a marker of tenderness, and comprises the sequence set forth in SEQ ID NO. 2, SEQ ID NO. 3, SEQ ID NO. 4 or combinations thereof. The compositions include primers that amplify markers of marbled or tender beef present in bovine animal or carcass genomes and hybridization probes to detect marbling or tenderness markers.

Abstract:
An immunoassay method including reacting a sample from a patient with a bispecific antibody, wherein the bispecific antibody includes one antibody specific for a compound to be detected and a second antibody specific for a compound foreign to said patient sample, and subsequently reacting the patient sample with a polymer probe, wherein the polymer probe includes a compound recognized by the second antibody in the bispecific antibody complex and further includes at least two detectable signals; the bispecific antibody; and the polymer probe of the immunoassay method are disclosed.
Abstract:
A highly sensitive method to detect melanoma micrometastasis by examining lymph nodes for the presence of tyrosinase messenger RNA. In a preferred mode, this is accomplished using the combination of reverse transcription and double round polymerase chain reaction (RT-PCR). The amplified samples are examined on a 2% agarose gel and tyrosinase is seen as a 207 base pair fragment. The lymph nodes examined are determined using pre- and intra- operative node mapping.
Abstract:
A lipolytic enzyme with high activity at alkaline pH in the absence of Ca.sup.++ can be obtained from strains of filamentous fungi belonging to the genus Absidia. The lipolytic enzymes are effective for improving the effect of detergents towards fatty soiling.
Abstract:
MYCELIA HAVING STRONG A-GALACTOSIDASE ACTIVITY AND VERY WEAK INVERTASE ACTIVITY ARE OBTAINED BY CULTURING A MOLD BELONGING TO THE GENUS ABSIDIA IN A CULTURE MEDIUM INCORPORATING THEREIN AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF LACTOSE, MELIBIOSE, RAFFINOSE AND GALACTOSE. WHEN BEET MOLASSES IS TREATED WITH THE SAID MYCELIA, RAFFINOSE CONTAINED IN THE MOLASSES IS DECOMPOSED INTO SUCROSE AND GALACTOSE. THUS, THE YIELD OF SUCROSE CAN BE INCREASED.
Abstract:
A lipase enzyme which hydrolyzes glycerides of long-chain carboxylic acids in preference to those of short-chain carboxylic acids can be produced by growing under aerobic conditions a culture of a strain of Absidia in a medium containing appropriate nutrients and then recovering the enzyme therefrom. An especially useful strain is Absidia butleri.
Abstract:
The invention relates to a new enzyme or urate oxidase which is very active in promoting oxidation of uric acid to allantoin. The urate oxidase is produced by fermentation under aerobic conditions of nutrient media containing sources of assimilable carbon, assimilable nitrogen and uric acid which have been seeded with suitable cultures of bacteria, fungi or yeasts. Isolation and purification of the urate oxidase is described.
