This disclosure is directed to methods for retrieving and using at least one lymphocyte. Additionally, cell receptor sequences identified with this strategy could be used for antibody development, TCR discovery, or appropriate therapeutics development or evaluation.

Method to identify antigen-specific immune cells

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.

Apparatus, system, and method for collecting a target material

This disclosure is directed to an apparatus, system and method for retrieving target material from a suspension. A system includes a processing vessel, a displacement fluid, and a tube. The tube includes a funnel, a cannula, and a cavity. The cannula allows for fluid communication between the funnel and the cavity, such that the processing vessel is inserted into the cavity, and the cannula extends into the processing vessel.

This disclosure is directed to an apparatus, system and method for introducing a liquid into a vessel. A fluid layering system includes a pump connected to a line connected to a connector, such that the connector provides an air-tight fit with the vessel.

Apparatus, system, and method for introducing a liquid into a vessel

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.

Apparatus, system and method for collecting a target material

This disclosure is directed to an apparatus, system and method for retrieving a target material from a sample. A fraction-density-altering solution may be added to a vessel that contains the sample to change the density of a first fraction of the sample without changing the density of the target material or the density of any other sample fraction. A collector may be inserted into the vessel to funnel the target material from the sample into the collector or into a processing receptacle included in the collector. In one implementation, the collector may include a cannula which extends from a funnel into a chamber to hold the processing receptacle. In another implementation, the processing receptacle may be inserted into a bore within the collector.

This disclosure is directed to an apparatus, system and method for retrieving a target material from a sample. A first depletion agent may be added to a vessel that contains the sample to change the density of a non-target material.

This disclosure is directed to an apparatus, system and method for retrieving a target material from a suspension. A system includes a primary vessel, such as a tube, a collector, and a two-part seal including an internal pliant part and an external constricting part. The internal pliant part may be a float and the external constricting part may be a sealing ring. The system may also include a processing vessel, such as an Eppendorf tube, a syringe or a test tube. The collector is sized and shaped to fit into a primary vessel and funnels the target material from the suspension through a cannula and into the processing vessel. 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.
