  • Patent number: 11977091
    Abstract: An analyzer having an inner chassis surrounded by a housing includes sample and dilution probes, a mixing housing including first and second mixing chambers, a flow cytometer including a flow cell, and sample and sheath pumps configured to perform first and second pluralities of tasks, respectively. The first plurality of tasks includes: aspirating sample into the sample probe, dispensing sample from the sample probe into the first and second mixing chambers, delivering first sample-dilution fluid mixture to the flow cell, and delivering second sample-dilution fluid mixture to the flow cell. The second plurality of tasks includes: dispensing sheath to the flow cell in cooperation with the delivery of the first sample-dilution fluid mixture to the flow cell, and dispensing sheath to the flow cell in cooperation with the delivery of the second sample-dilution fluid mixture to the flow cell.

  • Patent number: 7256182
    Abstract: The present provides methods and compositions that enable effective delivery of nucleic acids to desired cells, including to a solid organ such as a mammalian heart. The methods and compositions enable effective gene transfer and subsequent expression to a majority of cells throughout a solid organ such as the heart. Methods and compositions of the invention preferably provide enhanced vascular permeability that enables increased gene transfer to targeted cells, but without significant degradation or injury to endothelial cell layers. Global delivery of nucleic acid to an intact heart has been achieved with as little as 2 minutes of intracoronary exposure to the administered nucleic acid.

  • Patent number: 6607834
    Abstract: Polyester-containing multilayer biaxially-oriented polypropylene films are provided. According to the invention, a two- or three-layer polyester-containing cap layer is bonded to a monoaxially oriented polypropylene core, followed by orientation of the resulting composite in a direction transverse to the direction of orientation of the core layer. At least one tie layer is interposed between the core and the polyester. Advantageously, the polyester contains silicone fluid as a processing aid.
