Abstract:
The invention provides particle compositions having applications in nucleic acid analysis. Nucleic acid polymer particles of the invention allow polynucleotides to be attached throughout their volumes for higher loading capacities than those achievable solely with surface attachment. In one aspect, nucleic acid polymer particles of the invention comprise polyacrylamide particles with uniform size distributions having low coefficients of variations, which result in reduced particle-to-particle variation in analytical assays. Such particle compositions are used in various amplification reactions to make amplicon libraries from nucleic acid fragment libraries.
Abstract:
This invention relates to novel antibodies that bind with greater affinity to the factor VIIa/tissue factor (FVIIa/TF) complex than to tissue factor (TF) alone, do not compete for binding to TF with FVII and FX, an inhibit FX activation. The antibodies bind at the site of injury and prevent the initiation of thrombosis. The antibodies can be used to treat a variety of thrombotic conditions including but not limited to deep vein thrombosis, disseminated intravascular coagulation, and acute coronary syndrome.
Abstract:
A layered metal structure is provided in accordance with an aspect of the invention. The structure can be used, for example, to fabricate a conductive interconnect element for conductively interconnecting one or more microelectronic elements. The layered structure includes first and second metal layers each of which may include one or more of copper or aluminum, for example. An intervening layer, may include for example, chromium between the first and second metal layers, chromium being resistant to an etchant usable to pattern the first and second metal layers selectively to the intervening layer. An etchant such as cupric chloride, ferric chloride (FeCl3), a peroxysulfuric composition, or a persulfate composition may be used to pattern the first and second metal layers in such case.

Abstract:
A method for making a reusable mold for forming a microelectronic element package. The method including the steps of removing material from portions of a base to form recesses in the base and then depositing a mask material on at least some portions of the base.
Abstract:
A connection component for a microelectronic element includes a body of dielectric material having opposing first and second surfaces. A plurality of elongated leads extend through the body between the first and second surfaces. The leads have a first end accessible at the first surface and a second end accessible at the second surface. A layer of anisotropic conductive material overlies the first ends and the first surface of the body for electrical connection of the leads to a microelectronic element.
Abstract:
The present invention relates to the design, production and use of analogs of thrombomodulin (TM) that have the ability to enhance the thrombin-mediated activation of protein C but which have a significantly reduced ability to promote activation of thrombin-activatable fibrinolysis inhibitor (TAFI). These analogs are useful in, for example, antithrombotic therapy.
Abstract:
A microelectronic component connection is made by providing a lead, extending along the surface of a first element such as a semiconductor chip or wafer, such that at least a part of the lead adheres to the surface of the first element. The adhesion between this part of the lead and the surface of the first element is released by altering the temperature of at least this part of the lead. This part of the lead can then be peeled away from the surface of the first element. This part of the lead may be connected to a second element such as a microelectronic connection component, and the lead may be deformed by moving the elements relative to one another.
Abstract:
A semiconductor chip connection component having numerous leads extending side-by-side across a gap in a support structure, each lead having a frangible section to permit detachment of one end of the lead from the support structure in a bonding process. The frangible sections are formed by treating the lead-forming material in an elongated treatment zone extending across the regions occupied by numerous leads to provide a step defining a fracture point of the lead during a wire bonding process.
Abstract:
Metal leads are formed on a copper conductive layer by applying a first resist and a main resist over the first resist, and forming aligned openings in these resist. A bottom layer of cover metal such as gold is plated onto the copper conductive layer in these openings, followed by a principal metal such as copper. The main resist is then removed so as to expose edges of the principal metal layer. A jacket of cover metal is plated onto the exposed edges and surfaces of the principal metal layer. During this stage, the first resist prevents deposition of the cover metal except on the leads. The jacket merges with the bottom layer of cover material, so as to form a continuous coating extending around the perimeters of the leads. The first resist is removed, and the conductive layer is etched away. The cover metal protects the principal metal during the etching stage.
