摘要:
The invention generally relates to methods for quantifying an amount of enzyme molecules. Systems and methods of the invention are provided for measuring an amount of target by forming a plurality of fluid partitions, a subset of which include the target, performing an enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the subset. The amount of target can be determined based on the detected number.

High throughput system for in vivo screens on vertebrate larvae. The system includes a source of vertebrate larvae in a liquid medium and loading tube means for aspirating a larva. A detector assembly is provided to differentiate passage of a larva from bubbles and/or debris. An imaging means is provided for both confocal imaging and wide-field fluorescence imaging of the larva. A laser is provided for optical manipulation of the larva.

Multi-well plates having contoured well designs allow multi-stage high throughput parallel assaying of ion channels or ion transporters. A well of a multi-well plate has a bottom region that is sized and shaped to simultaneously accommodate a sensing electrode and a pipette for delivering test compounds, wash fluid, and optionally ligands. The multi-well plates when coupled with an instrument having a pipette head and an electrode plate facilitates fluidic contact between cells and fluids delivered via a pipette for washing of wells with buffers or other wash solutions for serial exposure of test cells to various reagents or other stimuli. The control and test experiments are performed on the same cell (or cells) in a single well.

Methods for generating physical maps for polynucleotides, such as genomic DNA, are disclosed herein. Also disclosed are methods for identifying the source of polynucleotides. The methods can, for example, be used in physical map construction of whole genome. In addition, methods and systems capable of performing high throughput characterization of macromolecules using nanofludic devices are enclosed.
摘要:
The present invention provides methods and kits for determining which microRNAs bind to a target mRNA where the methods comprise the steps of (a) creating a bait sequence from the target mRNA, where the bait sequence comprises a label that binds to a binding agent; (b) adding a mixture of microRNAs to the bait sequence; (c) separating the microRNAs that bind to the bait sequence from those microRNAs that do not bind; and (d) identifying the microRNAs that bind to the bait sequence, wherein the microRNAs identified are those that bind to the target mRNA.
