Upon addition of enzyme acceptor fragment (EA) and substrate to the assay mixture, the method allows for discrimination between ED free in solution and ED bound to the bead. The complexing of ED and EA provides an active ?-galactosidase enzyme. The method permits the assay of any substance involved in a pathway that can result in a reaction releasing the ED.Type: GrantFiled: July 12, 2002Date of Patent: May 22, 2012Assignee: DiscoverxInventors: Pyare Khanna, Shu-Ling Cheng

Publication number: 20120107836Abstract: The present invention relates to a kinase labelled at an amino acid naturally present or introduced in the P-loop of said kinase, wherein said labelling is effected at a free thiol or amino group of said amino acid and said label is (a) a thiol- or amino-reactive fluorophore sensitive to polarity changes in its environment; or (b) a thiol-reactive spin label, an isotope or an isotope-enriched thiol- or amino-reactive label, such that said fluorophore, spin label, isotope or isotope-enriched label does not inhibit the catalytic activity and does not interfere with the stability of the kinase. The invention furthermore relates to a method of screening for kinase inhibitors, a method of determining the kinetics of ligand binding and/or of dissociation of a kinase inhibitor and a method of generating mutated kinases suitable for the screening of kinase inhibitors using the kinase of the present invention.Type: ApplicationFiled: October 13, 2011Publication date: May 3, 2012Inventors: Daniel Rauh, Jeffrey Raymond Simard

Patent number: 8148093Abstract: This invention relates to a method for assessing risk of prostate cancer. Specifically, it relates to utilizing both Pro108 and Prostate Specific Antigen (PSA) in combination to determine the risk of prostate cancer. In addition, it is directed to a method for assessing risk of ovarian, colon, breast or stomach cancer utilizing Pro108 or specific antibodies to Pro108. The invention provides isolated anti-prostate, ovarian, colon, breast or stomach cancer antigen (Pro108) antibodies that bind to Pro108 on a mammalian cell in vivo. The invention also encompasses compositions comprising an anti-Pro108 antibody and a carrier. These compositions can be provided in an article of manufacture or a kit. Another aspect of the invention is an isolated nucleic acid encoding an anti-Pro108 antibody, as well as an expression vector comprising the isolated nucleic acid. Also provided are cells that produce the anti-Pro108 antibodies. The invention encompasses a method of producing the anti-Pro108 antibodies.Type: GrantFiled: October 3, 2007Date of Patent: April 3, 2012Assignee: diaDexus, Inc.Inventors: Iris Simon, Laura Corral, Charis Lawrenson, Nam Kim, Glenn Pilkington, Robert L.

Patent number: 8114583Abstract: A target and methods for specific binding and inhibition of RNA polymerase from bacterial species are provided, including methods for identifying agents that bind to a bacterial RNA polymerase, and that inhibit an activity of a bacterial RNA polymerase, through interactions with a bacterial RNA polymerase homologous switch-region amino-acid sequence. The methods can include preparation of a reaction solution comprising the compound to be tested and an entity containing a bacterial RNAP homologous switch-region amino-acid sequence, and detection of binding or inhibition. Applications in control of bacterial gene expression, control of bacterial viability, control of bacterial growth, antibacterial chemistry, and antibacterial therapy are also provided.Type: GrantFiled: November 5, 2009Date of Patent: February 14, 2012Assignee: Rutgers, The State University of New JerseyInventor: Richard H.
