Abstract: The invention provides methods, kits and materials for determinining simultaneously signature sequences of a population of tagged polynucleotides. Size ladders of polynucleotide fragments are generated from the population of tagged polynucleotides that contain a plurality of size classes. After the size classes are separated, tags of the separated fragment are copied and labeled according to the identity of one or more bases at the ends of the fragments. In a preferred embodiment, the labeled tags are then specifically hybridized to plurality of identical microarrays of tag complements such that the tags from different size classes are hybridized to separate microarrays. Signature sequences are determined by signals generated at hybridization sites having the same address on each of the plurality of microarrays.

Abstract: Methods for detecting the presence of foreign DNA in the DNA of a host organism are described. Probe libraries prepared from modified DNA, and from unmodified DNA, are competitively hybridized with reference DNA sequences cloned on solid phase supports, where the reference DNA sequences are characteristic of the foreign DNA. Probes containing the foreign DNA can thereby by isolated and/or identified.

Abstract: The present invention relates to protein-protein interactions of adipocytes, e.g., complexes of such polypeptides, polynucleotides encoding the polypeptides and complexes thereof, fragments of the polypeptides, antibodies to the complexes, Selected Interacting Domains (SID) which are identified due to the protein-protein interactions, methods for screening drugs for agents which modulate the interaction of proteins and pharmaceutical compositions that modulate the protein-protein interactions.

Abstract: Embodiments of the present invention feature nucleic acid and proteins derived from Mycobacterium tuberculosis and leprae. The proteins and nucleic acid of the present invention have applications in diagnostics and therapeutics.

Abstract: Living cells containing genetic material derived from recombinant DNA material and capable of expressing rennin, pre-prorennin and prorennin. The rennin, pre-prorennin and prorennin are derived from cells which are themselves or have had parents thereof treated by recombinant DNA methods to allow production of the desired enzymatic proteins during growth in culture.

Abstract: A DNA segment contains a GAL1 promoter of Saccharomyces cerevisae linked to a gene other than the galoctokinase gene, for directing the expression of the gene within a yeast cell.A GAL1 promoter portion of Saccharomyces cerevisae is linked to a foreign DNA segment for use in expressing a desired protein. Yeast cells containing the GAL1 promoter linked to a foreign DNA segment are grown in a medium containing glucose, wherein the yeast cells metabolize the glucose and are permitted to express a polypeptide when galactose is present in the medium.
