In some embodiments, an apparatus can include a water detector for analyzing the water concentration of a detritylation reagent to be reacted with a nascent oligonucleotide. An apparatus can comprise a feedback loop to control the concentration of water at the point of the detritylation reaction and/or to control the detritylation reaction time. The apparatuses and methods reduce batch-to-batch variations in the manufacture of oligonucleotides immobilized on the surface of various substrates.

  • Patent number: 8410252
    Abstract: The invention is directed to purified and isolated novel ULBP polypeptides, the nucleic acids encoding such polypeptides, processes for production of recombinant forms of such polypeptides, antibodies generated against these polypeptides, fragmented peptides derived from these polypeptides, and the uses of the above. ULBP polypeptide can be found on the surface of human B cell lymphomas. Mammalian forms of ULBP polypeptide in isolated or purified forms are provided. In addition, isolated nucleic acids encoding ULBP polypeptides and expression vectors comprising a cDNA encoding ULBP polypeptides are provided. The ULBP polypeptides can be isolated or synthesized and used to prepare antibodies, and in particular monoclonal antibodies, against the polypeptides. The antibodies, in turn, are useful for detecting the presence of ULBP polypeptides in human cell samples, which can be correlated with the existence of a malignant condition in a patient.

  • Patent number: 8404439
    Abstract: The present invention concerns the use of methods and compositions for the isolation of small RNA molecules (100 nucleotides or fewer), such as microRNA and siRNA molecules. Such molecules are routinely lost in commonly used isolation procedures and therefore the present invention allows for a much higher level of enrichment or isolation of these small RNA molecules.

  • Publication number: 20130065810
    Abstract: The present invention is related to a fungal serine protease enzyme, which comprises an amino acid sequence of the mature Fe_RF6318 enzyme having an amino acid sequence of SEQ ID NO: 15. The serine protease is obtainable from Fusarium equiseti, more preferably from the deposited strain CBS 119568. Also disclosed are nucleic acid sequences encoding said protease, such as plasmid pALK2521 comprising the nucleotide sequence SEQ ID NO:9 deposited in E. coli RF7664 under accession number DSM 22171 and plasmid pALK2529 comprising the full-length gene SEQ ID NO: 10 deposited in E. coli RF7800 under accession number DSM 22172. Said protease is useful as an enzyme preparation applicable in detergent compositions and for treating fibers, for treating wool, for treating hair, for treating leather, for treating food or feed, or for any applications involving modification, degradation or removal of proteinaceous material.
