Publication number: 20240133791Abstract: Methods of assessing the suitability of a fluorochrome panel for use in a flow cytometric protocol analyzing a biological sample are provided. Methods of interest include, with a processor, receiving an initial fluorochrome panel, a plurality of population identifiers each referring to a particle population, and an instrument identifier. Methods additionally include, creating a set of population-marker pairs, generating a set of separability metrics each predicting a measure of statistical distance between particle populations in flow cytometer data space, aggregating the set of separability metrics into a panel score, and evaluating the panel score. Systems and non-transitory computer readable storage media for assessing the suitability of a fluorochrome panel for use in a flow cytometric protocol analyzing a biological sample are also provided.Type: ApplicationFiled: July 26, 2023Publication date: April 25, 2024Inventors: Wenyu Bai, Peter Mage, Nikolay Samusik

Publication number: 20240100527Abstract: The present disclosure provides a support shelf for a histological container for use with multiple histological samples. The container can include shelf supports on interior sides of the container and orient the shelf at a downward angle for fluid flow. The shelf can support a plurality of sample slides across a support surface. The shelf can include an end support to maintain the slide on the support surface. To control fluid flow across the slide, the end support can encourage wicking to a wicking end support of the shelf in a controlled manner to maximize exposure of the specimen to the reagent and other fluids and reduce costs and expense of processing. Side rails at the side of the shelf help maintain slides on the shelf, and guide rails disposed inwardly from the side rails help maintain separation of the multiple slides placed on the shelf support surface.Type: ApplicationFiled: September 18, 2023Publication date: March 28, 2024Applicant: Parhelia Biosciences CorporationInventor: Nikolay SAMUSIK

Publication number: 20240091777Abstract: A histological container for histological samples is provided with a removable humidity control lid with portals for access into the container. The lid creates a humidified zone across the lid portals to allow processing steps inside the container while minimizing variations in the container humidity. A cover can be placed over the container for thermal control inside the container. The cover includes a top with portals aligned with the lid portals for access through the cover and top to inside the container. The cover can include a shutter slidably interfaced with the top. The shutter can include shutter portals selectively aligned with the top portals. Slidable alignment of the shutter portals with the top portals allows access to inside the container. Slidable nonalignment of the shutter portals with the top portals restricts access, essentially closing the container to control temperature levels and other ambient conditions inside the container.Type: ApplicationFiled: September 18, 2023Publication date: March 21, 2024Applicant: Parhelia Biosciences CorporationInventor: Nikolay SAMUSIK

Publication number: 20240091779Abstract: The present disclosure provides a cover pad for a histological container having an inclined shelf for a planar support with a histological sample coupled to a topside of the planar support and a cover pad over the planar support. The cover pad is generally planar with flow guiding surfaces that intersect downward flowing fluids deposited on the planar support. A spreader surface on the cover pad disperses fluids toward the cover pad sides. The spreader surface can be angled upward, as a convex curve, to direct impinging fluids along the angled surface toward the sides. Side flow guides intersect the spreader surface angle and smoothly flow the sideways directed fluids into a vertical space between the cover pad and the planar support. Side flow bars extend longitudinally upward above the side flow guides and assist in retaining fluids onto the planar support before the fluids engage the side flow guides.Type: ApplicationFiled: September 18, 2023Publication date: March 21, 2024Applicant: Parhelia Biosciences CorporationInventor: Nikolay SAMUSIK

Publication number: 20240091776Abstract: A support tile for a container for use with histological samples can be held at a downwardly inclined angle. A planar support, having a histological sample coupled to an underside, can be supported by the support tile with a space therebetween for fluids to flow through. The support tile top includes an inclined ramp for fluid deposition, beginning a flow path down the support tile. A spreader step disperses fluids more uniformly across the support tile. The spreader step can be angled, such as convex, facing the flow path direction and delay the fluid flow through the flow path central portion until flow is dispersed to the flow path sides for more uniform flow across the sample. An aggregator at a support tile bottom directs fluid flow from sides toward the flow path central portion for wicking of the fluid by an end stop to drain from the support tile.Type: ApplicationFiled: September 18, 2023Publication date: March 21, 2024Applicant: Parhelia Biosciences CorporationInventor: Nikolay SAMUSIK
