Patent number: 6777147Abstract: A method of evaluating process effects of multiple exposure photolithographic processes by first determining a set of expected images for each exposure step or process of the multiple exposure process individually and then obtaining a composite set of images by sequentially perturbing images from a first or previous exposure step by weighted images from the subsequent exposure step. Preferably, the expected images are determined by simulation in the form of normalized aerial images over a range of defocus for each exposure step, and the weighting factor used is the dose-ratio of the subsequent exposure dose to the prior step exposure dose. The resulting composite set of images may be used to evaluate multiple exposure processes, for example, to provide an estimate of yield for a given budget of dose and focus errors, or alternatively, to provide specifications for tool error budgets required to obtain a target yield.Type: GrantFiled: May 21, 2003Date of Patent: August 17, 2004Assignee: International Business Machines CorporationInventors: Carlos A.

Patent number: 6777176Abstract: The bacterial phosphotransferase system (PTS) as a drug target system catalyses the uptake and phosphorylation of carbohydrates. It is further involved in signal transduction, e.g. catabolite repression, chemotaxis, and allosteric regulation of metabolic enzymes and transporters. It is ubiquitous in bacteria but does not occur in eukaryotes. This uniqueness and the pleiotropic function make the PTS a target for the development of new antimicrobials. Assays are described that lead to the discovery of compounds which uncouple the PTS, by acting as protein histidine/cysteine phosphatases. Uncoupling of the PTS leads to inhibition of carbohydrate transport, repression of catabolite controlled genes (e.g. certain virulence genes) and depletion of phosphoenolpyruvate. Compounds from combinatorial libraries with high affinity for phosphoenolpyruvate-protein-phosphatase (Enzyme 1) serve as lead structures for the development of inhibitors and uncouplers of the PTS.Type: GrantFiled: April 30, 2001Date of Patent: August 17, 2004Assignee: Arpida AGInventors: Bernhard Erni, Seema Mukhija

Patent number: 6777189Abstract: One embodiment of the invention is a method of producing an oligonucleotide extended by a single nucleotide base. An oligonucleotide and an extension terminating nucleotide are mixed with an enzyme having terminal transferase activity. The reaction produces an oligonucleotide extended by a single base. The extended oligonucleotide may be used as a size standard for single base extension reactions. Another embodiment of the invention is a method of producing a mixture of oligonucleotides extended by different single bases. An oligonucleotide, a first extension terminating nucleotide, and a second extension terminating nucleotide are mixed with an enzyme having terminal transferase activity. The first and second extension terminating nucleotides comprise different nucleotide bases and are labeled with different labels. The identity of the different extension terminating nucleotides (and hence the extended oligonucleotides) may be ascertained by reference to the specific label incorporated.Type: GrantFiled: March 27, 2002Date of Patent: August 17, 2004Assignee: Applera CorporationInventors: Dong Wei, Danielle Bishop

Patent number: 6777190Abstract: Assay for detecting the amount or presence of target ligand in a sample. The assay includes a ligand analogue conjugate having a linkage site and a binding site, a ligand receptor, and a sample. The assay includes the steps of providing at least one crosstalk inhibitor. This inhibitor, under assay conditions, competes with the linkage site of the ligand analogue conjugate for binding to the ligand receptor, and does not compete with the binding site of the ligand analogue conjugate for binding to the ligand receptor. In the invention, the assay is performed for the target ligand in the presence of a sufficient amount of the crosstalk inhibitor to reduce the amount of binding of the linkage site of the ligand analogue conjugate to the ligand receptor. The invention also features a method for identifying crosstalk inhibitors, and the crosstalk inhibitors themselves.Type: GrantFiled: May 11, 1994Date of Patent: August 17, 2004Assignee: Biosite, Inc.Inventors: Kenneth F. Buechler, Richard R. Anderson, Theodore T. Lee, Gunars E. Valkirs

Patent number: 6777194Abstract: The present invention relates to monoclonal antibodies against the human Mcm3 protein, hybridoma cell lines that produce such antibodies, procedures for the production and their use, pharmaceutical compositions comprising a monoclonal antibody according to the present invention, their use for the prevention and treating of certain diseases as well as methods relating to the prevention and treatment of diseases associated with Mcm3 expression. Monoclonal antibodies according to the invention detect and bind human Mcm3 monospecifically both in immunohistological and immunobiochemical detection systems. The process for the production of these monoclonal antibodies comprises an initial screening of excess hybridoma supernatant with immunobiochemical methods followed by a second screening of positive hybridoma by means of an immunohistochemical method.Type: GrantFiled: January 28, 2002Date of Patent: August 17, 2004Assignee: Dakocytomation Denmark A/SInventors: Johannes Gerdes, Thomas Scholzen, Elmar Endi, Claudia Wohlenberg, Bettina Baron-Lühr, Margrit Kernbach Hahn, Patricia Prilla, Johanna Suwinski, Rolf Knippers
