  • Patent number: 10527526
    Abstract: Compositions and methods for preparing a sample for immunological staining are provided. Compositions include kits comprising a first solution comprising a surfactant and a second solution comprising a chaotropic agent. Methods comprise contacting a sample, such as cells or tissues, with a first solution comprising a surfactant and then contacting the sample with a second solution comprising a chaotropic agent. The method does not require extreme heat for antigen retrieval and therefore, maintains the cellular morphology of the sample.

  • Patent number: 8539625
    Abstract: A gap shield assembly for shielding an open area between a first section of a bed and an adjacent second section of the bed. The gap shield has a first shield member and a second shield member. The second shield member is rotatably connected to the second section of the bed. The first shield member is rotatably and translationally connected to the second shield member. The gap shield assembly also has a width extender assembly connecting the first shield member to the first section of the bed to allow the first shield member to move inwardly and outwardly with respect to a centerline of the bed while still shielding the open area between the first and second sections of the bed.

  • Patent number: 7899623
    Abstract: Methods and computer program products for evaluating and optimizing one or more markers for use in establishing a prognosis for a patient suffering from a disease are provided. More particularly, the methods include steps for systematically evaluating a number of features that may be extracted from an image of a body sample, such as a histological slide, that has been exposed to one or more biomarkers so as to establish a prognostic decision rule based on one or more of the extracted features such that the decision rule yields a prognosis that is optimally predictive of actual patient outcome. Thus, the methods and computer program products provided yield optimally predictive prognoses to assist clinicians in developing strategies for effective patient care management.
