摘要:
A method for collecting and delivering biological samples to a destination, such as an analyzer are provided herein. In one example, a plurality of samples, each including particles, is obtained from respective wells of a sample source having a plurality of wells. The plurality of samples are introduced into a fluid flow stream contained within a conduit having an inner diameter and in communication with a destination. An inner surface of the conduit is coated with a hydrogel barrier substance, such as poly-HEMA. The fluid flow stream is guided through the conduit to a destination. In one example, the destination may be a flow cytometer. Methods of preparing a poly-HEMA solution and coating the inner surface of a conduit with poly-HEMA are also provided.

摘要:
A flowcell for a sequencing instrument. The flowcell includes a fluid inlet, a fluid outlet, a flow channel formed between an at least partially transparent cover and a base and fluidly connecting the fluid inlet to the fluid outlet, and a capture substrate provided in the flow channel. The capture substrate includes microretainers configured to each receive a single microspot having a microspot diameter, and microretainer is separated from adjacent microretainers by an interstitial gap distance that is equal to or greater than the microspot diameter. A particle separator may be fluidly connected to the flowcell. The particle separator may include a microfluidic channel having an array of micropillars to transfer a plurality of the microspots to a loading buffer that may be delivered to the flowcell.

Provided herein is a method of analyzing a biological sample collected from a subject. An implementation of the method may include a) receiving, at a first site, data transmitted from a data acquisition device at a second site, wherein the data acquisition device is configured to i) read an output signal that is representative of the biological sample from a disk-coupled dots-on-pillar antenna array (D2PA) device comprising a D2PA to generate raw data that is representative of the biological sample, and ii) transmit data comprising the raw data to the first site, and b) analyzing the data at the first site to generate an evaluation of the data. In some embodiments, the method includes providing a process management operation such that the evaluation can be used for screening, diagnosis, or treatment of the subject. Also provided herein are systems that find use in implementing the method.
