Patent number: 11067487Abstract: This disclosure is directed to an apparatus, system and method for retrieving a target material from a suspension. A system includes a plurality of processing vessels and a collector. The collector funnels portions of the target material from the suspension through a cannula and into the processing vessels. Sequential density fractionation is the division of a sample into fractions or of a fraction of a sample into sub-fractions by a step-wise or sequential process, such that each step or sequence results in the collection or separation of a different fraction or sub-fraction from the preceding and successive steps or sequences. In other words, sequential density fractionation provides individual sub-populations of a population or individual sub-sub-populations of a sub-population of a population through a series of steps.Type: GrantFiled: January 8, 2017Date of Patent: July 20, 2021Assignee: RareCyte, Inc.Inventors: Daniel Campton, Joshua Nordberg, Steve Quarre, Ronald Seubert, Jonathan Lundt, Lance U'Ren

Publication number: 20180364136Abstract: This disclosure is directed to a method and an attachment solution for adhering a cytological or histological sample, such as buffy coat, to a substrate, such as a microscope slide. The attachment solution includes an attachment base, an anti-coagulant, and a nonsteroidal anti-inflammatory drug. The attachment base may be an alcohol, an acid, an oxidizer, an organohalogen, a ketone, or any combination thereof. Once a sample is obtained, the sample may be re-suspended in the attachment solution or the attachment solution may be added to the sample. The sample may then be dispensed onto an analysis platform as one or more droplets and cured.Type: ApplicationFiled: August 27, 2018Publication date: December 20, 2018Inventors: Daniel CAMPTON, Joshua NORDBERG, Ronald SEUBERT

Publication number: 20180238778Abstract: This disclosure is directed to an apparatus and method for spreading a fluid across a substrate. A spreader for spreading a fluid across a substrate includes a wiper and a frame. The wiper and the frame may mate to permit translation of the wiper across, and with respect to, the frame. The wiper spreads the fluid across the substrate and the frame supports the wiper and the substrate. The frame may also include a ramp to cause a portion of the wiper to lift away from the substrate.Type: ApplicationFiled: April 25, 2018Publication date: August 23, 2018Inventors: Joshua NORDBERG, Daniel CAMPTON, Steve QUARRE, David STEWART

Patent number: 10054524Abstract: This disclosure is directed to an apparatus, system and method for retrieving a target material from a sample. An enrichment agent may be added to a vessel that contains the sample for positive selection, or, in other words, to select or aid in selecting the target material from amongst the remainder of the sample. The enrichment agent may be, for example, immunomagnetic beads, buoyant beads, high-density beads, chemicals to change the density of the target material, or the like.Type: GrantFiled: November 2, 2016Date of Patent: August 21, 2018Assignee: RareCyte, Inc.Inventors: Daniel Campton, Joshua Nordberg, Steve Quarre, David Stewart, Ronald Seubert, Jonathan Lundt, Lance U'Ren, Jennifer Chow

Patent number: 9492819Abstract: This disclosure is directed to an apparatus, system and method for retrieving a target material from a suspension. A system includes a processing vessel, such as an Eppendorf tube, a syringe or a test tube, and a collector. The collector is sized and shaped to fit into a primary vessel, such as a test tube. The collector funnels the target material from the suspension through a cannula and into the processing vessel. The cannula extends into a cavity at a first end of the collector that holds the processing vessel. The collector includes a funnel at a second end in fluid communication with the cannula. In one implementation, the processing vessel includes at least one displacement fluid to be expelled, such that the at least one displacement fluid pushes the target material into the collector.Type: GrantFiled: April 1, 2015Date of Patent: November 15, 2016Assignee: RareCyte, Inc.Inventors: Daniel Campton, Joshua Nordberg, Steve Quarre, David Stewart, Ronald Seubert, Jonathan Lundt, Lance U'Ren

Patent number: 9440234Abstract: This disclosure is directed to a slide for analyzing target analytes of a suspension. The slide can be used to collect and hold the target analyte for imaging or further processing. The slide comprises a well section, including wells into which the target analyte can be stored. The wells may be removable and sized to fit into a second apparatus, such as a PCR thermocycler, for additional processing. Alternatively, the wells may hold processing vessels, such as PCR tubes, the processing vessels being used for downstream processing and/or analysis.Type: GrantFiled: March 20, 2014Date of Patent: September 13, 2016Assignee: RareCyte, Inc.Inventors: Joshua Nordberg, Jennifer Chow, Daniel Campton, Jonathan Lundt
