摘要: Methods, assays, and products for the detection of analytes in a sample are provided. In one aspect, for example, a device for detecting an analyte in a sample can include a fluid transfer membrane further including a sample input region operable to receive a liquid sample, a reagent region including a first split aptamer segment, a second split aptamer segment, and a detection marker, where the first and second split aptamers are operable to ligate in the presence of the analyte. The detection marker is operable to bind to the second split aptamer. The device can further include a test region having an immobilized binding reagent operable to bind to the first split aptamer segment such that the detection marker is held in the test region when the first split aptamer segment is ligated to the second split aptamer segment due to the analyte being present in the sample.

摘要: Methods, assays, and products for the detection of small molecules are provided. In one aspect, for example, a method of detecting a small molecule in a sample can include reacting together a first half of a DNA split aptamer having a first reactive group coupled thereto, a second half of a DNA split aptamer having a second reactive group coupled thereto, where the DNA split aptamer is selective for the small molecule, and a sample containing the small molecule. The first half and the second half bind to the small molecule and the first reactive group and the second reactive group react to form an aptamer ligation product of the first half and the second half. The method can also include assaying for the aptamer ligation product in order to detect the small molecule presence in the sample.

摘要: Systems, devices, and methods for capturing single source-specific biological material from a multi-source aggregate of biological material are disclosed and discussed. A capture system is generated using reversible chain-blocking to make capture substrates having substrate-linked populations of capture molecules specific for molecules of interest. Incubating such capture substrates in the presence of only a single source of biological material facilitates the association of molecules of interest from the same source. Capture substrate-specific barcode sequences coupled to the capture molecules allow multisource aggregate processing and subsequent grouping to retain the source-specific information following downstream processing.
