Abstract: The present disclosure provides methods for conducting in situ multiplex and multi-omics detection and identification using coded padlocks probes. The methods comprise simultaneous use of RNA-specific padlock probes and polypeptide-specific padlock probes to detect both RNA and polypeptides in a cellular sample. Both types of probes include a barcode that unique identifies the RNA or polypeptide that that padlock probe detects. Both types of probes also include a batch-specific sequencing primer binding site to enable sequencing a desired subset of concatemer template molecules. Use of the batch-specific sequencing primers reduces overcrowding signals and images, to produces optical images that are intense and resolvable. By conducting multiple rounds of sequencing on the same cellular sample using different batch-specific sequencing primers enables multiplex and multi-omics sequencing to reveal numerous target RNAs and their encoded polypeptides.

Abstract: Nucleic acid hybridization buffer formulations and uses thereof are described that yield improvements in hybridization specificity, rate, and efficiency. The buffer formulation composition includes a target nucleic acid; at least one organic solvent having a dielectric constant in the range of no greater than 115; and a pH buffer system, wherein the target nucleic acid is attached to the surface via hybridization to a surface bound nucleic acid tethered to the surface, and wherein the hybridization of the target nucleic acid and surface bound nucleic acid has a high stringency and annealing rate.

Abstract: Fluorescence imaging system designs are described that provide larger fields-of-view, increased spatial resolution, improved modulation transfer and image quality, higher spatial sampling frequency, faster transitions between image capture when repositioning the fields-of-view, improved imaging system duty cycle and a more compact system, and thus enable higher throughput image acquisition and analysis for genomics and other imaging applications at a lower cost.

Abstract: The present disclosure provides compositions and methods that employ the compositions for conducting pairwise sequencing and for generating concatemer template molecules for pairwise sequencing. The concatemers can be generated using a rolling circle amplification reaction which is conducted either on-support, or conducted in-solution and then distributed onto a support. The rolling circle amplification reaction generates concatemers containing tandem copies of a sequence of interest and at least one universal adaptor sequence. An increase in the number of tandem copies in a given concatemer increases the number of sites along the concatemer for hybridizing to multiple sequencing primers which serve as multiple initiation sites for polymerase-catalyzed sequencing reactions. When the sequencing reaction employs detectably labeled nucleotides and/or detectably labeled multivalent molecules (e.g., having nucleotide units), the signals emitted by the nucleotides or nucleotide units that participate in the parallel sequencing reactions along the concatemer yields an increased signal intensity for each concatemer.

Abstract: Methods and systems for detecting the presence of a target nucleic acid sequence in one or more samples of a plurality of samples are described. The methods may comprise the use of linear barcoded nucleic acid probes that, upon hybridization to a target nucleic acid sequence, may be ligated to circularize the probe molecule, amplified, and sequenced. The use of a probe-specific barcode integrated into the nucleic acid probe molecule, and sample-specific barcodes that may be incorporated into the nucleic acid probe molecule or added during the amplification step, enable large-scale multiplexed assay and sample processing.
