  • Cultured tissue transplant device
    Patent number: 9107982
    Abstract: A device for transplanting a graft such as a layer or layers of cultivated, autologous, allogenic or xenogenic cells to cover an accidental or surgical wound. The graft is cultivated and carried on a bed of collagen or other dissolvable or releasable material mounted on a protective substrate molded to conform to the profile of the wounded area and provided with a lateral attachment zone. The device facilitates the graft cultured in vitro to the recipient surface.
    Type: Grant

  • Method for nucleic acid amplification and detection using adhered probes
    Patent number: 5888723
    Abstract: Nucleic acids can be amplified and detected using an element which has a sealable support on which is disposed a nucleic acid reagent composition. The composition is a mixture of a nucleic acid reagent composed of polymeric particles to which an oligonucleotide is covalently attached. The particles are prepared from a first polymer having a glass transition temperature of at least about 70.degree. C. and have an average diameter of from about 0.1 to about 3 micrometers. The reagent is adhered to the support using a water insoluble adhesive comprising a second polymer which has a glass transition temperature which is at least about 30.degree. C. less than the glass transition temperature of the first polymer. The adhesive is present in the composition at from about 1 to about 20 dry weight percent. The method provides high sensitivity and low background in the assay of nucleic acids, preferably using polymerase chain reaction.
