Patent number: 9567378Abstract: The present invention relates to a method of directing in situ oriented immobilization of a protein on a support. This method involves providing a support and contacting the support with a solution. The solution comprises (a) a protein comprising a coupling moiety and (b) a molecule comprising a first group reactive with the support and a second group reactive with the coupling moiety. The molecule binds (i) the support at the first group and (ii) the coupling moiety at the second group, thereby immobilizing and orienting, in situ, the protein on the support. Also described are a protein array and a method of screening compounds for protein interaction.Type: GrantFiled: June 3, 2011Date of Patent: February 14, 2017Assignee: New York UniversityInventors: Daniel C. Propheter, Lara K. Mahal

Publication number: 20120302514Abstract: Disclosed are compositions containing glycoconjugates and methods for making the functionalized glycoconjugates, which include (a) contacting a cell with a first monosaccharide, and (b) incubating the cell under conditions whereby the cell (i) internalizes the first monosaccharide, (ii) biochemically processes the first monosaccharide into a second saccharide, (iii) conjugates the saccharide to a carrier to form a glycoconjugate, and (iv) extracellularly expresses the glycoconjugate to form an extracellular glycoconjugate comprising a selectively reactive functional group. Methods for forming products at a cell further comprise contacting the functional group of the extracellularly expressed glycoconjugate with an agent that selectively reacts with the functional group to form a product. Subject compositions include cyto-compatible monosaccharides comprising a nitrogen or ether linked functional group selectively reactive at a cell surface and compositions and cells comprising such saccharides.Type: ApplicationFiled: October 30, 2007Publication date: November 29, 2012Inventors: Carolyn Bertozzi, Kevin J. Yarema, Lara K. Mahal

Publication number: 20020160505Abstract: A method and device for controlled cell adhesion is provided. The device comprises lipid bilayer membranes arranged into discrete areas in a micro-array. They are useful for screening and modulation of living cell adhesion and growth on a solid substrate. The lipid bilayer membranes are doped with various lipids and/or proteins to modulate the adherence of the cells being used in the device.Type: ApplicationFiled: February 13, 2002Publication date: October 31, 2002Inventors: John T. Groves, Lara K. Mahal, Carolyn R. Bertozzi
