Abstract: Multivalent binding compositions including a particle-nucleotide conjugate having a plurality of copies of a nucleotide attached to the particle are described. The multivalent binding compositions allow one to localize detectable signals to active regions of biochemical interaction, e.g., sites of protein-protein interaction, protein-nucleic acid interaction, nucleic acid hybridization, or enzymatic reaction, and can be used to identify sites of base incorporation in elongating nucleic acid chains during polymerase reactions and to provide improved base discrimination for sequencing and array based applications.

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.
