  • Patent number: 5683560
    Abstract: A magnetic yoke (22,23) carrying rows of permanent magnets (33,34) and a target (49,50) is connected to a top plate (41,42) by spring bolts (67) which urge the yoke toward the top plate. Rotatable cams (43,44) between the top plate and the yoke are used to adjust the distance between the top plate and the yoke. Clamping bars (37,38) having a claw-like edge parts (59-66) limit the maximum distance and, in a preferred embodiment, hold the target against the yoke.

  • Patent number: 5681751
    Abstract: A first reactant is immobilized i.e. in a porous matrix (50), adjacent a sample electrode (46) within a reaction chamber. Energizing of the electrode (46) electrophoretically attracts a mobile second reactant and/or electrolytically induces appropriate reaction conditions to enhance reaction of the first and second reactants. Polarity reversals between the sample electrode (46) and remote electrodes (38), (42), (44) cause unreacted second reactant and/or by-products to migrate away from the immobilized first reactant. The techniques are useful for sequential chemical reactions such as sequencing or construction of proteins, polysaccharides and nucleic acids where cyclical additions and removals of reactants are required. The techniques are amenable to automated micro and nano scale construction and operation and allow direct electrophoretic (38) interfacing with chromatographic, HPCE and mass spectrophotometric equipment.

  • Patent number: 5679535
    Abstract: An apparatus for collecting antigen, including an allergen exemplified by a dust-mite, dispersed in a motile fluid in a given environment that can be inserted in a section of a pipe of a standard vacuum cleaner hose. The apparatus includes a receptacle whose body is formed of nylon, typically with a pore size of from 15 to 60 .mu.m. The receptacle is coated with an antibody that retains the antigen in a contacting relationship. The apparatus is provided with a removable holder, which assists in locating the apparatus in the pipe of the vacuum cleaner. The apparatus can be used directly in an immunoassay for confirming the presence of, or quantifying, the antigen.

  • Patent number: 5677441
    Abstract: Process for the production of oligonucleotides of formula II, in which the exocyclic amino groups of the bases adenine, guanine, cytosine, 7-deazaadenine and 7-deazaguanine carry N-phenylacetyl groups, are used for oligonucleotide synthesis, wherein in a first step a starting nucleotide is bound to a solid carrier, subsequently the desired oligonucleotide is synthesized by stepwise coupling with appropriately activated further monomeric nucleotide building blocks of the general formula I with the above-mentioned meanings, if desired, trivalent phosphorus is oxidized to pentavalent phosphorus during and after the synthesis, the oligonucleotide is cleaved from the carrier and the 5' protecting groups are cleaved off. The phenylacetyl functional groups that protect exocyclic NH.sub.2 groups of the bases can be cleaved off in a mild way with penicillin amidohydrolase (EC 3.5.1.11).
