Abstract:
The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and/or detection of particles, such as cells and/or beads. The invention provides systems, including apparatus, methods, and kits, for the microfluidic manipulation and/or analysis of particles, such as cells, viruses, organelles, beads, and/or vesicles. The invention also provides microfluidic mechanisms for carrying out these manipulations and analyses. These mechanisms may enable controlled input, movement/positioning, retention/localization, treatment, measurement, release, and/or output of particles. Furthermore, these mechanisms may be combined in any suitable order and/or employed for any suitable number of times within a system. Accordingly, these combinations may allow particles to be sorted, cultured, mixed, treated, and/or assayed, among others, as single particles, mixed groups of particles, arrays of particles, heterogeneous particle sets, and/or homogeneous particle sets, among others, in series and/or in parallel. In addition, these combinations may enable microfluidic systems to be reused. Furthermore, these combinations may allow the response of particles to treatment to be measured on a shorter time scale than was previously possible. Therefore, systems of the invention may allow a broad range of cell and particle assays, such as drug screens, cell characterizations, research studies, and/or clinical analyses, among others, to be scaled down to microfluidic size. Such scaled-down assays may use less sample and reagent, may be less labor intensive, and/or may be more informative than comparable macrofluidic assays.
Abstract:
Methods, systems, and devices are described for multiple single-cell capturing and processing utilizing microfluidics. Tools and techniques are provided for capturing, partitioning, and/or manipulating individual cells from a larger population of cells along with generating genetic information and/or reactions related to each individual cell. Different capture configurations may be utilized to capture individual cells and then processing each individual cell in a multi-chamber reaction configuration. Some embodiments may provide for specific target amplification, whole genome amplification, whole transcriptome amplification, real-time PCR preparation, copy number variation, preamplification, mRNA sequencing, and/or haplotyping of the multiple individual cells that have been partitioned from the larger population of cells. Some embodiments may provide for other applications. Some embodiments may be configured for imaging the individual cells or associated reaction products as part of the processing. Reaction products may be harvested and/or further analyzed in some cases.

Abstract:
This disclosure provides a method of forming tagged nucleic acid sequences. A target polynucleotide is immobilized on a solid support; a recognition-oligonucleotide is hybridized thereto; the recognition-oligonucleotide-target polynucleotide hybrid is cleaved; and an adapter nucleic acid is ligated to the cleaved target polynucleotide, thereby forming a tagged nucleic acid sequence. Also provided is a method of forming a tagged single stranded cDNA; a method of forming a plurality of tagged heterogeneous nucleic acid sequences; a library of recognition-oligonucleotides; and methods for amplifying a cDNA sequence immobilized on a solid support. These methods and products can be used alone or in combination for integrated single cell sequencing, and can be adapted for use in a microfluidic apparatus or device.
