  • Patent number: 10077300
    Abstract: Activatable binding polypeptides (ABPs), which contain a target binding moiety (TBM), a masking moiety (MM), and a cleavable moiety (CM) are provided. Activatable antibody compositions, which contain a TBM containing an antigen binding domain (ABD), a MM and a CM are provided. Furthermore, ABPs which contain a first TBM, a second TBM and a CM are provided. The ABPs exhibit an “activatable” conformation such that at least one of the TBMs is less accessible to target when uncleaved than after cleavage of the CM in the presence of a cleaving agent capable of cleaving the CM. Further provided are libraries of candidate ABPs, methods of screening to identify such ABPs, and methods of use. Further provided are ABPs having TBMs that bind VEGF, CTLA-4, or VCAM, ABPs having a first TBM that binds VEGF and a second TBM that binds FGF, as well as compositions and methods of use.

  • Patent number: 10017757
    Abstract: The present invention provides compositions including peptide display scaffolds that present at least one candidate peptide and at least one detectable moiety in at least one of the N-terminal and C-terminal candidate peptide presenting domains that when expressed in a cell are accessible at a surface of the cell outermembrane. In addition, the present invention also provides kits and methods for screening a library of cells presenting the candidate peptides in peptide display scaffolds to identify a ligand for an enzyme.

  • Publication number: 20180002687
    Abstract: Methods of making and using bacterial display polypeptide libraries using circularly permuted OmpX (CPX) variants are disclosed. The invention further relates to methods for enhancing the display of proteins and peptides at the surface of bacteria by optimizing linkers and incorporating mutations at positions 165 and 166 of CPX.

  • Patent number: 9849494
    Abstract: An automated bender and its method of operation according to some embodiments of the disclosure is provided. The automated bender includes a carousel which has all of the necessary components for bending a variety of conduit sizes provided thereon. The carousel can be rotated to a desired bending position to bend a particular type of conduit. A straight workpiece is fed into the automated bender and a bent workpiece, which may have multiple bends therein, is output from the automated bender. This bending process is performed without manual intervention. Software for achieving same is provided.

  • Patent number: 9663304
    Abstract: A rotary chuck includes a clamp assembly, a first drive mechanism for operating the clamp assembly to clamp an associated workpiece, a frame rotationally fixed to the clamp assembly, and a second drive mechanism for rotating the frame and the clamp assembly. The second drive mechanism can rotate the frame and the clamp assembly around 360 degrees. A pair of alignment springs are engaged with a mounting plate upon which the second drive mechanism is mounted. The mounting plate can pivot relative to a stable surface to which it is mounted, and the springs limit the pivotal movement. Each first and second drive mechanism includes a motor, and are connected to a microprocessor for operation of the respective motor.
