Abstract: Disclosed herein include systems, methods, compositions, and kits for determining expressions of proteins and genes simultaneously, and for sample indexing. The method can comprise extending a cellular component-binding reagent specific oligonucleotide hybridized to an oligonucleotide barcode to generate an extended cellular component-binding reagent specific oligonucleotide. The extended cellular component-binding reagent specific oligonucleotide can be separated from the oligonucleotide barcodes. The separated extended cellular component-binding reagent specific oligonucleotide can be amplified separately from barcoded cDNA.

Abstract: Disclosed herein include systems, methods, compositions, and kits for 5?-based gene expression profiling and for whole transcriptome analysis (WTA) with random priming and extension (RPE). Blocker oligonucleotides capable of specifically binding to a portion of an oligonucleotide barcode are provided in some embodiments. The blocker oligonucleotides can reduce of the generation of undesirable extension products, such as, for example, the extension products of random primers hybridized to a portion of the oligonucleotide barcode. Immune repertoire profiling methods are also provided in some embodiments.

Abstract: Disclosed herein include systems, methods, compositions, and kits for labeling nucleic acid targets. Some embodiments provide oligonucleotide barcodes comprising a cleavage region. The cleavage region can comprise one or more cleavage sites. In some embodiments, cleaving agents are capable of effectuating cleavage of a phosphodiester backbone of the cleavage region. The oligonucleotide barcode can be associated with a solid support. Methods of separating barcoded nucleic acid molecules from the solid support are also provided in some embodiments.

Abstract: Disclosed herein include systems, apparatuses, devices, and methods for introducing one or more components into a fluid. A first fluid and a second fluid can be co-injected into a fluidic channel of a flow cell. In some embodiments, the first fluid and a second fluid are immiscible (e.g. an aqueous buffer and a non-aqueous liquid). In some embodiments, the second fluid is less dense than the first fluid.

Abstract: The invention provides methods and compositions for detecting a mutation in a target gene in a sample of blood or a fraction thereof, including in certain examples, a fraction that includes circulating tumor DNA. The methods can include a tiling PCR reaction, for example a one-sided multiplex tiling reaction. Virtually any type of mutation can be detected with the methods and compositions. In certain embodiments, gene fusions are detected. Improved PCR methods, especially for performing nested multiplex PCR reactions are provided.

Abstract: A modified thermostable Pol B DNA polymerase, produced by a reaction, under essentially aqueous conditions, of a thermostable Pol B DNA polymerase and a modifier reagent of Formula I wherein the reaction results in a thermally reversible inactivation of the thermostable Pol B DNA polymerase activity and the 3?-5? exonuclease activity, which polymerase is suitable for hot-start PCR. Also disclosed are the method for the modification, a polynucleic acid amplification method and PCR reaction mixture and kit comprising the modified thermostable Pol B DNA polymerase.

Abstract: Embodiments include methods, compositions, and kits for creating genetic libraries useful for massively parallel genetic sequencing. Some embodiments are directed to methods of preventing the contamination of genetic libraries with material generated during the formation of other genetic libraries. In some embodiments, the methods employ adapters comprising universal priming sites. The methods can employ non-ligatable primers to generate non-ligatable amplification products so as to prevent unwanted ligation to adapters. In some embodiments, the non-ligatable primers contain uracil. Genetic material can be treated with uracil N glycosylase to prevent the unwanted ligation of uracil containing amplicons to adapters used for creating a second genetic library.
