Integrated devices that include a sample preparation component integrated with a detection component are disclosed. The sample preparation component may be a digital microfluidics module or a surface acoustic wave module which modules are used for combing a sample droplet with a reagent droplet and for performing additional sample preparation step leading to a droplet that contains beads/particles/labels that indicate presence or absence of an analyte of interest in the sample. The beads/particles/labels may be detected by moving the droplet to the detection component of the device, which detection component includes an array of wells.

Devices and methods for sample analysis

Integrated devices that include a sample preparation component integrated with a detection component are disclosed. The sample preparation component may be a digital microfluidics module or a surface acoustic wave module which modules are used for combing a sample droplet with a reagent droplet and for performing additional sample preparation step leading to a droplet that contains beads/particles/labels that indicate presence or absence of an analyte of interest in the sample. The beads/particles/labels may be detected by moving the droplet to the detection component of the device, which detection component includes an array of wells. The detection modules disclosed here can be used for detecting analytes of interest which analytes may have been enriched by amplification, isolation, or other techniques.

Methods, devices, and systems for analyte analysis using a nanopore are disclosed. The methods, devices, and systems utilize a first and a second binding member that each specifically bind to an analyte in a biological sample. The method further includes detecting and/or counting a cleavable tag attached to the second binding member and correlating the presence and/or the number of tags to presence and/or concentration of the analyte. Certain aspects of the methods do not involve a tag, rather the second binding member may be directly detected/quantitated. The detecting and/or counting may be performed by translocating the tag/second binding member through a nanopore. Devices and systems that are programmed to carry out the disclosed methods are also provided.

The invention provides a lysis reagent and method for preparing a test sample for use in an assay, wherein the method yields a homogeneous lysis mixture suitable for use in automated pipetting systems without the need for a centrifugation step. The lysis reagent includes a glycol and non-specific animal immunoglobulins. Other aspects of the invention include related immunoassays and test kits.

The present disclosure provides among other things immunoassays exhibiting reduced cross-reactivity with analyte metabolites. Additionally, the present disclosure provides diagnostic immunoassays to determine the concentration or level in a test sample of a hydrophobic drug that metabolizes in vivo or in vitro to form cross-reacting metabolites wherein cross-reactivity with such metabolites of the drug analyte is reduced. In particular, the disclosure provides such immunoassays where the hydrophobic drug is an immunosuppressant drug such as cyclosporine A.

Methods and kits for measurement of concentration of FK778 in a biological sample by means of an immunoassay, preferably a competitive immunoassay. In one aspect, the method and kit involve the use of (a) an antibody to FK778 conjugated to a label, e.g., an acridinium label, (b) an antibody to FK778 not conjugated to a label, (c) a solid phase containing an antibody to a first hapten, e.g., a fluorescein hapten, and (d) a bihapten comprising a first hapten and FK778 or an analogue of FK778, e.g., a bihapten comprising a fluorescein hapten and a FK778 hapten. In another aspect, the method and kit involve the use of (a) antibody to FK778, (b) a bihapten comprising FK778 or an analogue of FK778 and a first hapten, e.g., a bihapten comprising the fluorescein hapten and the hapten of FK778 or an analogue of FK778, and (c) a pretreatment reagent.
