  • Patent number: 8921055
    Abstract: In some cases, the described systems and methods include obtaining a cell sample containing multiple antibody-producing cells. In such cases, the cells can be tagged with a cross-linking reagent having a first portion configured to bind to a marker on the antibody-producing cells and a second portion configured to bind to an antigen of interest. In some instances, the tagged antibody-producing cells are exposed to the antigen of interest such that the antigen becomes bound to the cells. In some such instances, the antibody-producing cells are also allowed to produce an antibody, such that a portion of the antibody-producing cells produce an antigen-specific antibody that binds to the antigen of interest. To identify cells that produce the antigen-specific antibody, the tagged cells can be exposed to a labeled secondary antibody that is configured to bind to the antigen-specific antibody. Other implementations are also described.

  • Patent number: 8921057
    Abstract: A CDK profile including a ratio of specific activities of two cyclin dependent kinases closely correlates with the malignancy grade and the presence/absence of the sensitivity to an irritant such as an anticancer agent of a cancer tissue in clinical medicine. Therefore, the properties of a mammalian cell, such as malignancy grade, proliferation potency, sensitivity to an irritant such as an anticancer agent can be assessed based on its CDK profile or by comparing the result of a specific activity ratio of two CDKs with a predetermined threshold corresponding to the ratio. This sensitivity assessing method shows a high ratio of correct assessing results particularly in positive or sensitivity and is useful in predicting efficacy of chemotherapy using the anticancer agent.

  • Patent number: 8921064
    Abstract: A naturally occurring or recombinant protein, especially a mutein of porcine urate oxidase (uricase), that is essentially free of large aggregates can be rendered substantially non-immunogenic by conjugation with a sufficiently small number of strands of polymer such that the bioactivity of the protein is essentially retained in the conjugate. Such conjugates are unusually well suited for treatment of chronic conditions because they are less likely to induce the formation of antibodies and/or accelerated clearance than are similar conjugates prepared from protein preparations containing traces of large aggregates.

  • Patent number: 8921085
    Abstract: Manufacturing methods and compositions are described for production of self-contained microfluidic cartridge devices with on-board reagents for molecular biological testing. Sensitive reagents are stored in dry form without lyophilization or freezing, and reconstituted at the point of use with either a biological sample or a sample eluate at the point of use. Manufacturing methods include sheet and roll fabrication processes where the reagents are printed in place and sealed within individual microfluidic cartridges before gel vitrification.

  • Patent number: 8921087
    Abstract: A process for the propagation of Theobroma cacao L. by somatic embryogenesis using explant material which is subjected to a) primary embryogenesis in the dark in a solid culture medium causing induction and expression to produce primary embryos, b) secondary embryogenesis i) in which the primary embryos are treated in the dark in a solid or liquid culture medium to produce and multiply embryogenic callus followed by ii) treatment of the embryogenic callus in the dark in a suitable liquid culture medium causing expression of the embryogenic callus to produce further new secondary embryos, c) pre-germination of the secondary embryos in a Petri dish on a solid medium, or in a bioreactor in a liquid medium, into pre-germinated secondary embryos at the cotyledonary stage, d) ex-vitro germination of the pre-germinated secondary embryos at the cotyledonary stage by sowing directly on a culture substrate in the greenhouse to produce the plantlets, and e) development of the plantlets.

  • Patent number: 8921092
    Abstract: A system and method are described for electroporating a sample that utilizes one or more sets of electrodes that are spaced apart in order to hold a surface tension constrained sample between the electrodes. The first electrode is connected to the lower body of the system while the second electrode is connected to the upper body. Both electrodes are connected to a pulse generator. Each electrode has a sample contact surface such that the first electrode and the second electrode may be positioned to hold a surface tension constrained sample between the two sample contact surfaces and the sample may receive a selected electric pulse.
