  • Patent number: 9581587
    Abstract: A method of sex sorting sperm is disclosed. The sperm may be stained with a DNA selective fluorescent dye, which fluoresces when excited, a dead quenching dye, which selectively quenches fluorescence emitted by the DNA selective fluorescent dye within the membrane of compromised sperm, and a split enhancing dye. The stained sperm may then sorted into one or more gender enriched subpopulations of viable sperm.

  • Patent number: 9421318
    Abstract: The present disclosure relates generally to systems for processing a unit of whole blood into its components while the unit is still in the centrifuge. The system comprises a container holding whole blood and one or more satellite bags or containers that are installed into a holder, which is then inserted into a bucket of the centrifuge. Tubes interconnect the containers, one or more of which are preferably installed into clamping mechanisms resident in the holder. The holder further preferably includes sensing means, such as optical sensors, to sense the location of the interfaces between the separated layers of the whole blood that result from rotation of the centrifuge.

  • Patent number: 9416420
    Abstract: There is a need or improved methods for determining the diagnosis and prognosis of patients with conditions, including autoimmune disease and cancer, especially lymphoid neoplasms, such as lymphomas and leukemias. Provided herein are methods for using DNA sequencing to identify personalized, or patient-specific biomarkers in patients with lymphoid neoplasms, autoimmune disease and other conditions. Identified biomarkers can be used to determine and/or monitor the disease state for a subject with an associated lymphoid disorder or autoimmune disease or other condition. In particular, the invention provides a sensitive method for monitoring lymphoid neoplasms that undergo clonal evolutions without the need to development alternative assays for the evolved or mutated clones serving as patient-specific biomarkers.

  • Patent number: 9375516
    Abstract: A growth factor delivery scaffold combines a heparin/fibrin-based delivery system (HBDS) with a backbone based on polymer nanofibers for tissue (e.g., tendon and ligament) repair. The scaffold has improved surgical handling properties compared to the gelatinous consistency of the prior art HBDS system and retains the capability for delivering mesenchymal cells and controlling the release of growth factors. One application for the scaffold is mesenchymal stem cell (MSC) therapy for flexor tendon repair. The scaffold can deliver growth factors in a sustained manner, can be implanted for flexor tendon repair, is biocompatible, and is not cytotoxic. The growth factor delivery scaffold may also be used in the surgical repair of an injury to bone, muscle, cartilage, or other tissues.

  • Patent number: 9347933
    Abstract: Provided herein are systems and methods for improving yield of sorted particles. In one embodiment, for example, there is provided a system including: (a) a flow cytometer to analyze a sample, wherein the flow cytometer provides a parameter plot based on the analysis of the sample; (b) a user-interface, wherein a user can define a coincidence acceptance gate in the parameter plot, and wherein the coincidence acceptance gate identities a non-target particle population in the sample that may be accepted with a target particle in a subsequent sort analysis; and (c) a sort analysis system to sort particles within the sample, while accepting particles defined by coincidence acceptance gate.
