  • Patent number: 6998260
    Abstract: Disclosed is a method of expressing enzymatically-active, recombinant proteolytic tryptase in a eukaryotic host cell, expression constructs which drive the production of enzymatically-active tryptase in transformed hosts, and genetically-engineered eukaryotic host cells containing the expression constructs and which express enzymatically-active proteolytic tryptases. Uses for the proteolytic tryptases so produced are also disclosed. Also disclosed is a method of making active site mutants of proteolytic tryptases in a eukaryotic host cell, expression constructs which drive the production of the mutants in transformed eukaryotic host cells, and genetically-engineered eukaryotic host cells containing the expression constructs and which express the active-site mutated form of proteolytic tryptases.

  • Patent number: 6677140
    Abstract: The present invention entails methods and kits for carrying them out based on the discovery that an RNA replicase, such as Q&bgr; replicase, has DNA-dependent RNA polymerase (“DDRP”) activity with nucleic acid segments, including DNA segments and DNA:RNA chimeric segments, which comprise a 2′-deoxyribonucleotide or an analog thereof and which have sequences of RNAs that are autocatalytically replicatable by the replicase.

  • Publication number: 20020192677
    Abstract: The present invention entails methods, and kits for carrying them out, based on the discovery that an RNA replicase, such as Q&bgr; replicase, has DNA-dependent RNA polymerase (“DDRP”) activity with nucleic acid segments, including DNA segments and DNA:RNA chimeric segments, which comprise a 2′-deoxyribonucleotide or an analog thereof and which have sequences of RNAs that are autocatalytically replicatable by the replicase. The discovery of this DDRP activity provides methods of the invention for nucleic acid amplification wherein a nucleic acid, with a DNA segment with the sequence of an RNA that is autocatalytically replicatable by an RNA replicase, is provided as a substrate for the replicase. The replicase catalyzes synthesis, from the DNA segment, of the RNA, which the replicase then autocatalytically replicates. The invention entails use of the amplification methods in detecting nucleic acid analytes, as in nucleic acid probe hybridization assays.
