  • Patent number: 11964126
    Abstract: A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes at least one optical sensor assembly configured to sense the movement of the pump assembly, a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

  • Patent number: 5578463
    Abstract: Novel vectors are disclosed for expressing and secreting heterologous polypeptides from filamentous fungi. Such vectors are used in novel processes to express and secrete such heterologous polypeptides. The vectors used for transforming a filamentous fungus to express and secrete a heterologous polypeptide include a DNA sequence encoding a heterologous polypeptide and a DNA sequence encoding a signal sequence which is functional in a secretory system in a given filamentous fungus and which is operably linked to the sequence encoding the heterologous polypeptide. Such signal sequences may be the signal sequence normally associated with the heterologous polypeptides or may be derived from other sources. The vector may also contain DNA sequences encoding a promoter sequence which is functionally recognized by the filamentous fungus and which is operably linked to the DNA sequence encoding the signal sequence.

  • Patent number: 5389536
    Abstract: A substantially enzymatically pure hydrolase is provided which is secreted by and isolatable from Pseudomonas mendocina ATCC 53552. Cloning the gene expressing the hydrolase into a suitable expression vector and culturing, such as fermenting the E. coli strain JM101 harboring a plasmid designated pSNtacII, has been found to provide surprisingly high yields of the hydrolase.

  • Patent number: 5093257
    Abstract: Novel circular vectors containing a recplicable DNA sequence and DNA sequences encoding all or part of at least two distinct parental polypeptides are disclosed. Such vectors are used in novel processes utilizing in vivo recombination to produce recombined circular vectors containing said replicable DNA sequences and hybrid DNA sequences comprising: (1) a first DNA sequence encoding the amino-terminal portion of a hybrid polypeptide corresponding to a first part of a first parental polypeptide sequence and (2) a second DNA sequence encoding a carboxy-terminal portion of said hybrid polypeptide corresponding to a first part of a second parental polypeptide sequence. The hybrid DNA sequences of such recombined circular vectors can exprress novel hybrid polypeptides such as hybrid enzymes in general and in particular hybrid amylases and proteases. Various other processes are disclosed to isolate the recombined circular vector containing said hybrid DNA sequences.

  • Patent number: 5030240
    Abstract: An enzymatic perhydrolysis system, useful for bleaching, has a novel enzyme, a substrate, and a source of hydrogen peroxide, and provides in situ formation of peracid in aqueous solution. The substrate is selected for enzyme catalyzed reaction, and preferably is an acylglycerol with two or three fatty acid chains. The enzyme is hydrolytically and perhydrolytically active even in the presence of anionic surfactants, has lipase activity, and is isolatable from Pseudomonas putida ATCC 53552.

  • Patent number: 4963495
    Abstract: Direct linkage of DNA encoding prokaryotic signals such as E. coli enterotoxin with DNA encoding mature eukaryotic proteins followed by transformation and culture of bacterial hosts characterized by a periplasmic space, yields substantial amounts of periplasmic mature protein.

  • Patent number: 4859600
    Abstract: The production of mature hGH in E coli and Pseudomonas strains transformed by a plasmid which encodes pre hGH (comprising the signal polypeptide and the hormone itself) is described. These prokaryotes process the pre-hGH to cleave the signal sequence and, thereby, produce mature hGH.
