Abstract: The present invention provides a monoclonal anti-idiotype antibody 11D10 that elicits an immune response against a specific epitope of a high molecular weight mucin of human milk fat globule (HMFG) and a hybridoma that produces 11D10. The hybridoma that produces 11D10 was selected by specific procedures. 11D10 induces an immunological response to HMFG in nice, rabbits, monkeys and patients with advanced HMFG-associated tumors. This invention provides compositions derived from polynucleotide sequences encoding the variable light and/or variable heavy regions of monoclonal anti-idiotype antibody 11D10, as well as polypeptides encoded thereby. The invention also provides compositions which can be used in the detection or treatment of HMFG-associated tumors.

Abstract: Bone marrow (BM) is the major organ where immune cells are derived. Homeostasis in the BM is maintained by inter- and intra-cellular interactions by the various subsets of BM cells. The present invention discloses the cloning of a new cDNA from stimulated BM stromal cells that was retrieved with a probe specific for the neurokinin-1 (NK-1) receptor. The cloned cDNA was designated ‘Hematopoietic Growth Factor Inducible Neurokinin-1 type’ (HGFIN) gene based on its expression in differentiated hematopoietic cells. Hence, the present invention provides a novel gene, HGFIN, which encodes a protein receptor that is involved in the regulation of hematopoietic proliferation and differentiation.

Abstract: The present invention relates to PNA derivatives which carry, at the C terminus, or at both the C and N termini of the PNA backbone, one or more phosphoryl radicals. The phosphoryl radicals carry, where appropriate, one or more labeling groups, groups for crosslinking, groups which promote intracellular uptake, or groups which increase the binding affinity of the PNA derivative for nucleic acids. The invention furthermore relates to a process for preparing the above-mentioned PNA derivatives and to their use as pharmaceuticals or diagnostic agents.

Abstract: A method and apparatus for fabricating an array of biopolymers on a substrate using a biopolymer or biomonomer fluid, and using a dispensing head. The head has a reservoir chamber and at least one jet which can dispense droplets onto a substrate. The jet includes a capillary delivery chamber communicating with the reservoir chamber, which delivery chamber has an orifice. The jet further includes an ejector which, when activated, causes a droplet to be ejected from the orifice. The method includes loading the head by positioning the head with the orifice adjacent and facing a biomonomer or biopolymer fluid, and providing a load pressure to the reservoir chamber. The load pressure is sufficiently negative such that the fluid is drawn into the reservoir chamber through the orifice and delivery chamber, while simultaneously being insufficient to result in ambient atmosphere entering the delivery chamber through the orifice once the head has been loaded and no further fluid is facing and adjacent the orifice.

Abstract: The invention concerns a method for identifying and/or cloning nucleic acid regions representing qualitative differences associated with alternative splicing events and/or with insertions, deletions located in RNA transcribed genome regions, between two physiological situations, comprising either hybridization of RNA derived from the test situation with cDNA's derived from the reference situation and/or reciprocally, or double-strand hybridization of cDNA derived from the test situation with cDNA's derived from the reference situation; and identifying and/or cloning nucleic acids representing qualitative differences. The invention also concerns compositions or banks of nucleic acids representing qualitative differences between two physiological situations, obtainable by the above method, and their use as probe, for identifying genes or molecules of interest, or still for example in methods of pharmacogenomics, and profiling of molecules relative to their therapeutic and/or toxic effects.

Abstract: The invention provides arrays of polynucleotide probes having at least one pooled position. A typical array comprises a support having at least three discrete regions. A first region bears a pool of polynucleotide probes comprising first and second probes. A second region bears the first probe without the second probe and a third region bears the second probe without the first probe. A target nucleic acid having segments complementary to both the first and second probes shows stronger normalized binding to the first region than to the aggregate of binding to the second and third regions due to cooperative binding of pooled probes in the first region. The invention provide methods of using such arrays for e.g., linkage analysis, sequence analysis, and expression monitoring.

Abstract: Covalently bound non-polar tags are used to increase the retention times of double stranded polynucleotides on Matched Ion Polynucleotide Chromatography (MIPC) columns. In doing so, separations of DNA mixture components is improved. Additionally, when the non-polar tags are fluorophores, detection limits are also greatly reduced. Strategically tagged primers are used in conduction with PCR to produce DNA fragments having specifically tagged strands. This improves mutation detection by MIPC in several ways. Separations are improved, detection sensitivity is enhanced, and non-stoichiometric addition of wild type DNA prior to hybridization is now possible since only tagged fragments will be observed with a fluorescence detector. Non-polar tags are also used as a novel alternative to G-C clamping during MIPC under partially denaturing conditions. Reversible DNA binding dyes, such as DNA intercalator dyes and DNA groove binding dyes, are used to reduce the detection limit of polynucleotides separated by MIPC.

Abstract: Methods, compositions and articles of manufacture for assaying a sample for an amplification product from a target polynucleotide are provided. An amplification reaction is used to produce the amplification product from the target polynucleotide so that it can be used to indirectly assay the sample for the target polynucleotide. A sample suspected of containing the target polynucleotide is contacted with first and second primers to amplify the target polynucleotide; the first primer comprises a tag sequence, the complement of which is formed on the opposite strand during amplification and is referred to as a capture sequence. That opposite strand is referred to as a second primer extension product or an amplification product, and comprises a label. A capture probe is provided that is conjugated to a substrate and can bind to the capture sequence to form an amplification product detection complex.

Abstract: A method for detecting and/or quantifying a target DNA or RNA present in a sample by a isometric primer extension method is disclosed. The method includes carrying out a primer extension reaction in the absence of a free nucleotide so that the primer extension reaction is stopped where the absent nucleotide would have been inserted. Thus, as the amount of incorporation of a labeled nucleotide on the primer extended product is detected, the amount of the target RNA or DNA in the sample is measured.
