Patent number: 9539570Abstract: 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 30, 2015Date of Patent: January 10, 2017Assignee: RareCyte, Inc.Inventors: Lance U'Ren, Daniel Campton, Joshua Nordberg, Steve Quarre, Jonathan Lundt

Patent number: 9519002Abstract: This disclosure is directed to a device and a system for picking a target analyte of a suspension. A picker introduces at least one force, such as by a magnetic gradient and/or by a pressure gradient, to extract the target analyte from a specimen. The magnetic gradient may be introduced by a magnet, such as a permanent magnet or an electromagnet, and the pressure gradient may be introduced by a pump which moves within a fluid-primed cannula to create the pressure gradient, thereby drawing the target analyte into the cannula. The picker may also expel the target analyte onto or into a substrate, such as a well plate, after the target analyte has been drawn into the picker by reversing the pressure gradient or removing the magnetic gradient.Type: GrantFiled: April 9, 2014Date of Patent: December 13, 2016Assignee: RareCyte, Inc.Inventors: Joshua Nordberg, Steve Quarre

Patent number: 9417174Abstract: This disclosure is directed to systems and methods for analyzing target materials of a suspension include a tube and a float. The float may include expandable portions. The system traps a target analyte between the expandable float and the tube and/or to create a seal between the expandable float and the tube to inhibit fluid from flowing past the expandable float in the tube. The expandable portions may radially expand when exposed to an expanding fluid, such that the expanding fluid is not a naturally-occurring constituent of the suspension; or, the expandable portions may radially expand when a force is exerted upon the expandable portion. A tube may include expandable portions that expand towards the float.Type: GrantFiled: January 28, 2014Date of Patent: August 16, 2016Assignee: Rarecyte, Inc.Inventors: Daniel Campton, Joshua Nordberg, Evan Castiglia

Publication number: 20160045915Abstract: Systems for analyzing target materials of a suspension include a tube and a float in which at least a portion of the float is porous. The at least one pore can allow for the flow of fluids and reagents out of the float and into a space between the outer surface of the float and the inner surface of the tube. The at least one pore can also prevent unwanted particles or material from flowing into the float. The introduction of additional fluids, such as fixing agents, washing agents, detergents, or labeling agents, may aid in further processing or detection of the target analyte. The porosity of the float may also allow for the target analyte to be extracted through the float by introducing a removal device, such as a vacuum, to draw the target analyte through the float and into the vacuum.Type: ApplicationFiled: August 11, 2015Publication date: February 18, 2016Applicant: RareCyte, Inc.Inventors: Jonathan Lundt, Joshua Nordberg

Publication number: 20150241426Abstract: This disclosure is directed to a method for detecting an infection within a suspension without having to directly detect the infectious agent or without having to wait until symptoms of infection are present within the host. Once a sample is obtained, infectious agent-specific antibodies conjugated with labeling molecules are added to the biological sample. The infection may be detectable despite the absence of the infectious agent during detection because antigens released by the infectious agent may still be present on or within a biological component of the sample. The sample may undergo imaging to detect the infection.Type: ApplicationFiled: February 10, 2015Publication date: August 27, 2015Applicant: RareCyte, Inc.Inventors: Eric Kaldjian, Joshua Nordberg
