    摘要: The present invention provides compositions and methods for a reverse transcription reaction using a reversibly inactivated reverse transcriptase enzyme. The reversibly inactivated reverse transcriptase enzyme results from a chemical modification which inactivates the reverse transcriptase enzyme. The activity of the reverse transcriptase enzyme is recovered by an incubation of the reaction mixture at elevated temperature prior to, or as part of the reverse transcription reaction. The reverse transcriptase enzyme of the present invention provides for a signficant reduction in non-specific reverse transcription from template nucleic acid molecules because the formulation of the reaction mixture does not support the formation of reverse transcription products prior to activation of the reverse transcriptase.

    摘要: A bioabsorbable implantable device for replacing sutures in construction of a composite graft in ligament replacement surgery. In certain embodiments the device has a female component and a male component where the female component receives and secures the male component. In other embodiments the components of the device are in the shape of a rivet or a staple. The bioabsorbable implantable devices can be used for securing tendon grafts to bone blocks and for holding together the fibers of the tendon graft when the bone-tendon-bone graft is inserted into a patient during surgery. The bioabsorbable implantable device may also be part of a package for use in surgery. The package includes a sterile container for holding at least a graft that is of a predetermined length and width. The package may also include bone blocks. The package is marked as to the graft size including the width and the length of the graft. The graft and the bone blocks may be autogenous, allogenic or constructed from man-made materials.
