  • Patent number: 10047144
    Abstract: The invention provides methods of purifying antibodies using various antibody-specific purification media to rapidly and efficiently separate mixtures of antibodies, antibody fragments and/or antibody components to isolate a desired antibody product from the mixture. The invention relates to the purification of bispecific monoclonal antibodies carrying a different specificity for each binding site of the immunoglobulin molecule, e.g., antibodies composed of a single heavy chain and two different light chains, one containing a Kappa constant domain and the other a Lambda constant domain, including antibodies of different specificities that share a common heavy chain. The invention also provides the methods of efficiently purifying intact antibodies by separating the intact antibody from non-intact antibodies including free light chains.

  • Patent number: 10034847
    Abstract: ?-Substituted ?-amino acids, ?-substituted ?-amino acid derivatives, and ?-substituted ?-amino acid analogs and (bio)isosteres and their use as chemotherapeutic agents are disclosed. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres are selective LAT1/4F2hc substrates and exhibit rapid uptake and retention in tumors expressing the LAT1/4F2hc transporter. Methods of synthesizing the ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and methods of using the compounds for treating cancer are also disclosed. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs exhibit selective uptake in tumor cells expressing the LAT1/4F2hc transporter and accumulate in cancerous cells when administered to a subject in vivo. The ?-substituted ?-amino acid derivatives and ?-substituted ?-amino acid analogs and (bio)isosteres exhibit cytotoxicity toward several tumor types.

  • Publication number: 20180057611
    Abstract: The invention relates to antigen-binding proteins or antibodies having heterodimers of heavy chains, i.e., two immunoglobulin heavy chains that differ by at least one or two amino acid(s) that allows for isolation of the antigen-binding protein based on a differential affinity of an immunoglobulin heavy chain and a modified/mutated immunoglobulin heavy chain toward an affinity reagent. The invention also relates antigen-binding proteins, including bispecific antibodies, having IgG CH1 regions with different affinities with respect to affinity reagent(s) that allows rapid isolation by differential binding of the IgG regions to the affinity reagent(s).

  • Patent number: 9888283
    Abstract: Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

  • Publication number: 20180034625
    Abstract: A method to protect a device key in a device comprising at least one secure element locally connected to at least one time programmable memory storing a global value in form of a bit string comprising locked bits and unlocked bits. The locked bits are irreversibly pre-programmed in the one-time-programmable memory during an initialization phase of the device while the unlocked bits remaining in an initial state may be programmable by the secure element. The secure element is configured to generate, at initialization of the device, a device specific value by using the global value, program the device specific value previously obtained in the one time programmable memory, and erase the global value by programming the unlocked bits of the corresponding bit string. A further object of the disclosure includes a device configured to carry out the method.
