Provided herein are methods directed to multiplexed detection of the modulation of transcriptional activity using perturbation elements.

The present disclosure provides methods of patterning cells on a surface of a substrate. The methods include disposing a pattern of nucleic acids on a surface of a substrate, and contacting the patterned nucleic acids under hybridization conditions with a first suspension of cells, where cells of the first suspension include cell surface-attached nucleic acids complementary to the patterned nucleic acids, and where the cell surface-attached nucleic acids hybridize to the patterned nucleic acids to pattern the cells on the surface of the substrate. Systems and kits for practicing the methods are also provided.

A flexible, thin, elongated band is used as a substrate. Similarly to a magnetic tape, the band is unwound from a feed reel and is transported past an outlet opening of a receptacle containing the cells such that the cells are poured onto the band. Subsequently, the band containing the cells applied thereon is wound onto a take-up reel. The take-up reel is fixed on a drive shaft which can be rotated by a drive mechanism. The rotation thus achieved has the effect that the band is unwound, transported past the outlet opening and finally wound up. In addition, spacers are provided at the upper surface of the band in order to prevent the contacting of radially adjacent sections of the band containing the cells in a wound-up state.

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 enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the sunset. The amount of target can be determined based on the detected number.

The present invention relates to a technique for genomic library screening and provides a method for separating, capturing, analyzing, and retrieving cells and cell products by using a microstructure that can be preferentially applied to the field of antibody engineering for the development of new therapeutic antibodies and can be extensively applied to multiple genetic/phenotypic analysis of various biochemical molecules, for example, in the field of protein engineering and metabolic engineering.

According to the invention, generally, a method for making a microfluidic aliquoting (MA) chip, adapted to fit in a Petri dish, has a center well (inlet) connected by branched channels to a plurality of side wells (outlets). The chip comes in various types, including a bMA Chip T1, bMA Chip T2, bMA Chip T3, and an rMA Chip. The branched channel improvement provides for a greater distance between neighboring channels and a decreased density near the center well. Design improvements including an injection mold design for an insert and a base and a multiplex hole punch allow for rapid fabrication of the MA chip.

The present invention provides novel microfluidic devices and methods that are useful for performing high-throughput screening assays and combinatorial chemistry. The invention provides for aqueous based emulsions containing uniquely labeled cells, enzymes, nucleic acids, etc., wherein the emulsions further comprise primers, labels, probes, and other reactants. An oil based carrier-fluid envelopes the emulsion library on a microfluidic device, such that a continuous channel provides for flow of the immiscible fluids, to accomplish pooling, coalescing, mixing, sorting, detection, etc., of the emulsion library.

The present disclosure provides a fabrication process that results in creating large arrays of living cells, such as stem cells, which are subsequently exposed to nanoliter quantities of compounds to test the efficacy on cellular metabolism.
