  • Patent number: 9556280
    Abstract: Antibodies are disclosed that bind to and inhibit the anti-coagulant function of TFPI and have a lower affinity for TFPI at pH 6.0 than at pH 7.4. The lower affinity at pH 6 improves circulating half-life (T½) due to reduced target mediated clearance, a process by which an antibody/antigen complex is endocytosed and trafficked to the lysosome where both components are degraded. The lower affinity at pH 6.0 results in disruption of the complex prior to lysosome targeting and allows for re-circulation of the antibody. Specific modifications to antibody binding by histidine residue substitution are disclosed along with methods of use.

  • Patent number: 9556291
    Abstract: The present disclosure is directed to a process for producing olefin-based polymer in a gas phase polymerization reactor. The process includes forming a wet zone in the gas phase polymerization reactor. The wet zone is formed by maintaining a temperature less than or equal to the fluidizing medium dew point temperature+2° C. in a region of the reactor. The region is defined as the region extending from the distributor plate to 2.5 meters above the distributor plate. Injection of a high activity catalyst composition in the wet zone produces olefin-based having a settled bulk density greater than 23.5 lb/ft3.

  • Patent number: 9556292
    Abstract: The present invention aims to reduce excess scattering in light emitting arrangements. A composition comprising a transparent matrix comprising an anionic organic moiety, and metal cations dispersed in the matrix is disclosed. The anionic organic moiety and the metal cations form an organometallic complex, and wherein the metal cations are capable of forming transparent nano-crystals upon contact with an agent comprising at least one element selected from the group consisting of sulfur and selenium. Also an optical composition comprising a transparent matrix comprising an organic moiety residue, and unmodified nanocrystals is disclosed. Further, a method of preparing an optical composition comprising the steps of: providing a transparent matrix comprising an anionic organic moiety; dispersing metal cations into the matrix; and contacting the organometallic complex with an agent in order to in situ convert at least part of the metal cations into transparent nanocrystals.
