Abstract: The disclosure provides for methods, compositions, and kits for multiplex nucleic acid analysis of single cells. The methods, compositions and systems may be used for massively parallel single cell sequencing. The methods, compositions and systems may be used to analyze thousands of cells concurrently. The thousands of cells may comprise a mixed population of cells (e.g., cells of different types or subtypes, different sizes).

Abstract: Multiple unique selection probes are provided in a single medium. Each selection probe has a sequence that is complementary to a unique target sequence that may be present in a sample under consideration. For example, each selection probe may be complementary to a sequence that includes one of the SNPs used to genotype an organism. Single-stranded selection probes anneal or hybridize with sample sequences having the unique target sequences specified by the selection probe sequences. Sequences from the sample that do not anneal or hybridize with the selection probes are separated from the bound sequences by an appropriate technique. The bound sequences can then be freed to provide a mixture of isolated target sequences, which can be used as needed for the application at hand.

Abstract: Methods for amplifying genomic DNA using semi-random primers that consist of different combinations of two non-complementary bases are disclosed. In a preferred aspect all of the primers in the collection are composed entirely of the same two non-complementary bases. In preferred aspects the DNA is amplified using R6, Y6, M6 and K6. The amplification is by a strand displacing polymerase and the amplification product may be hybridized to a high complexity array of probes without further complexity reduction. In some aspects, additives are included in the hybridization to reduce non-specific hybridization. The hybridization pattern obtained is preferably analyzed for allele specific hybridization to determine genotype. The primers in the collection are selected so that there is a minimum of self complementarity between any two primers in the collection, minimizing the occurrence of hybrids between primers.

Abstract: Disclosed are techniques for reliably detecting target sequences in a complex nucleic acid sample, typically in the range of about 400 MB or greater, without employing a complexity reduction technique. The method employs relatively high quantities of a hybridization competitor, e.g., multiple times the amount of nucleic acid sample present. When the sample and competitor come in contact with nucleic acid probes complementary to target sequences, for an appropriate length of time under defined hybridization conditions (buffer composition, temperature, etc.), the target and probe hybridize reliably.

Abstract: Various embodiments of the invention provide human secreted proteins(SECP) and polynucleotides which identify and encode SECP. Embodiments of the invention also provide expression vectors, host cells, antibodies, agonists, and antagonists. Other embodiments provide methods for diagnosing, treating, or preventing disorders associated with aberrant expression of SECP.

Abstract: The present invention provides a method in which cDNAs that encode signal sequences for secreted or membrane-associated proteins are isolated using a fusion protein that directs secretion of a molecule that provides antibiotic resistance, e.g., &bgr;-lactamase. The present method allows the isolation of signal peptide-associated proteins that may be difficult to isolate with other techniques. Moreover, the present method is amenable to throughput screening techniques and automation, and especially in validating the presence of the signal sequence via expression of the protein in both prokaryotic and eukaryotic cells. This invention provides a powerful and approach to the large scale isolation of novel secreted proteins.
